should have washed it first though
whats the spec of the engine???
seems high bearing in mind the std EFI box is on there...
oh and mmmmm love the slanty kill yer engine RR lol

land and sea are the most accurate dyno there is mate, its got astra gte engine with btb manifold, full stainless system and superchip ecu
and how do you know its "the most accurate" ? lol
and when was the engine last rebuilt? as its going to have lost a ton of power from being old and doggy ;) not stealing your thunder or anything jsut those mods cant "really" give you 20bhp,,,

well its one of the most accurate, engine has only done 68k and is still very strong, just cos u maybe have a ****t engine that dont produce the bhp i mean sorry if ive got more power if u think its wrong then ill take it to a dyno of your choice
lol i wouldnt care if i had a pedalo and you had a 1000bhp liner :p
how do YOU know its accurate? have you calibrated it personally?
i know of no dyno that is "accurate" but id get an engine, RR it then modify it and take it back to the same RR with similar weather conditions to get a difference reading... as opposed to taking the power numbers as gospel.
even if you had std power a chip and exhaust wont add 20bhp... but i guess you dont understand engine fundamentals
What was the BHP figure at the wheels?
good ol stu !! i should 'introduce' you to all the people on cruise derby who calculted his power like this
"well courtenay advertise there de-cats as +10bhp, then the manifold is +15bhp, plus a superchip +20bhp and then a filter is +8bhp so yes my astra is 203bhp"
lol
i wont say much on the subject and stu has said the main valid points and got abuse in return, for those in the know, think of chris t's recent results, then firstly check the torque figure and where it is, then follow it along to the cross over point.
i'm sorry matt, stu was right in what he was saying and the truth generally sucks if you are not aware (everyone has been there and have done the same until they have been around abit).

well on that dyno the hart of the system is the data logging and that is one of the best in the world from www.land-and-sea.com (http://www.land-and-sea.com) have a look.
all dyno's are different the only way to get a true Engine BHP figure is with an Engine dyno that has no losses between the engine and the torque arm that is attached to the absorption unit ,but the engine needs removed to do this
i appreciate what you are trying to say, and yes your are spot on, the only true guage is to remove the engine and do a proper job.
the link you have supplied is kind of useless tho, as they are trying to sell the item so it will obviosly be the best on the planet. they wouldnt exactly sell many if they said it was of an average standard and would match many of the others available.
The false results dished out country wide are not so much the machinery but the operators themselves. there are ways of falsifying results, thus you get a nice big figure and are chuffed then tell your mates, they use the same people in the hope of again nice big results and the loop of dragging in extra trade starts. its the oldest trick in the book and over the years i have found myself travelling upto 3 hours just to get to a r/r with a no frills you gets what you gots attitude after being ripped off many times and learning the hard way myself without any advise from others

All very true points. Theres loads on contributeing factors to a RR result. I use Stevens rollers as its no frills. No fancy posters on the walls, no chav's in looking for a superchip on there 1.2 clio.
And i dont use them to get a figure, i use them as more of a health check. If you get a nice figure then generally your engines running nice and healthy. You can also get fueling mixture results etc.
So from your results matthew, i'd say thats a really good going XE with plenty of life left in it!

Good power figures you have there. just so you can compare heres my results.
Below is my rolling road result from jam motorsport of northampton.
As you see the slight difference in torque. Amazed your xe is on par with me tho at only 2k as well ?? Obviously there must be summat wrong with mine??

cheers keith, its only done 68 genuine and gets serviced regularly so its still a good strong motor
its worth noting that you "graph" is pointless too... no offence here but its power vs time... not rpm so you cant compare it to someone elses graph etc..... might be the best machineary about but if the monkey running it cant use it you may aswell draw your own graph from your **** dyno
thats 4rse dyno btw not something else the swear filter might deny lol
That torque figure is on a par with a certain peppermint nova with TB's....
Shurely Shome Mishtake???
rick, there is no point looking at his graph. its done on the wrong axis.....
stu's a homo lol lol , just read that and double glanced the graph again and i hate him :p although my views dont change along with everyone elses lol
wise words from keith, end of the day as long as it goes well and feels a million dollars the rest doesnt matter ( just take note of peoples views for future reference regardless of how daft they seem now :thumb: )

see chris. you wasted your time with TB's and cams..... :p

yeah its a fit old girl like, i would never bother putting my car on the rollers cos its cheaper coming on here and just letting some random guy tell me the power of my car ,
go post on mig then... you'll get a far more honest opinion of "it being a goodun" lmao

holy moly !!
i rolling roaded my car 2 months ago , done 4 runs , and the readings were all different .
8-9 bhp difference in some runs , just worked out the average of all the runs .
dont suppose thats right tho :roll:
aww sorry am i supposed to suck matts cock like the rest of you just because of some car he purchased.... it dosent make him invincible from ropey dyno results ffs.....
the engine "could" be 170 bhp and its just simply not the spec hes telling us/knows about... the usual "shes a goodun" or "its a special lump" just dont hold out with people who understand engines.
Rollers are out all over the place due to operator spazzyness DEAL WITH IT

lmao!!
y would we want to suck his cock?????
we are just stating that the red nova is very quick for what it is
early xe engines were 156bhp so there is every chance that it could be a 170bhp
you dont tend to gain 15bhp from an exhaust and "chip".... thats all.... but i guess max power adding like in the first page works well dosent it ;)
a cunning operator could have swung 200bhp if he thought it would make the owner wet himself lol

Hey Stu have you been waiting for a thread like this just to go off on one about what you think know about rolling roads???
No one gives a ****! Give it a god dam rest please!
Whats wrong with buying a car some one else has built? If I had a ferrari would you think I was a nob head because I didnt build it myself? lol

Just as a comparison. Beow are the graphs for my old XE lump taken on Courtenay's rollers not long after they were installed. On the same rollers I have had 3 standard cars (all within 3yrs old) that put out near book figures.
My engine spec at this time was headwork, cams, powercap and grpN chip. The engine had done about 10k after a FULL rebuild.

173.3 bhp & 160 lbft.
Your bhp may not be too far out but your torque figure seems a little higher at 173.

well funnely enough pal the red one is not far behind the green one because ive had them side by side and i know this because i own both lmfao
and your point is? That the rolling road is inaccurate for both cars?
Or are you trying to say that Bretts old car doesn't make any more power for the TB's and MBE than your red one? If that's the case, what a waste of money!
I can't see it personally, the fundamentals of the internal combustion engine (air+spark+fuel=power+torque) usually mean that a better ecu (more fuel)and TB's (more airflow) produce an increase.
I went to Power Zone at Padiham in Lancs while my mate picked up some stuff for his Mini, and a guy went on the rollers in a saxo vtr and ran 103bhp. They sold him an air filter (!) and re-ran it at 127bhp!!!!! Standard car! People tell you what you wanna hear!

must of been 1 of those 'max power' universal filters !!
LOL at this thread...
I am with the majority though, unlikely that you have anywhere near what the 'rollers' say..
I certainly wouldnt put my car anywhere near those rollers.. above 7000 rpm and the tappits would be screaming for their oil back!!!lol
Good luck pal, I am sure you have the quickest XE on here. Go post on Mig, that will shut you up! ;)
I'd only take my car on the rollers for diagnostics and tuning to get it running nicely, couldn't give a rats backside about the actual power output. It feels decidedly sickly at the moment so an expensive trip to interpro may be in order lol
As long as it runs good thats all that matters IMO

17-10-06, 10:41 AM
All this guy did was post up some decent pics and some info about his rolling road session and straight away the Fcukin nob heads who think they know everything jump on and start dishing out the ****e!
Give it a break!!!!!!!!!!!! No one want compulsive physics lectures so shut it!
Everyone with half a brain knows that a rr wont be 100% accurate, but it gives a good indication if your car is running well or not doesnt it?!
Once again the know it all's bringing down the site
would you rather be fed a laod of bull by an RR operator then go off "bragging" or in a fast n furious styleeeeeee do something silly like "race for slips" lol thinking you have 500bhp when in reality your running a misfiring briggs and stratton lol........
was only pointing out that numbers (and a useless graph, its not Vs Rpm so its kinda irrelevant) dont mean much unless its say lap times or 1/4 mile times (with a weight and gearbox setup)...... never mind you lot seem take RR's as gospel and things a tad toooooooo seriously. if ive annoyed you then Good :D

17-10-06, 11:12 AM
Id rather trust my own knowledge thanks but I appreciate people posting interesting threads up like matt did!
I think that this ranks alongside "Timed my SR 0-60 in 7 seconds with a stopwatch!" and "Mod chip off ebay gives 20bhp" in the point that the figures given are meaningless with no benchmark to go up against. I remember Iand Storeys virtually standard XE giving 200bhp at Powerzone a few years ago (Was in Redline!) but std SR's were giving over 100!
Play nicely now boys!!!
lol :tosser: lol
Once again the know it all's bringing down the site
not really imo or should we believe all the "gaskells" when they say there oven chips give 20bhp lol
Stuart - youve got to be the most miserable c**t on here, pretty much every post you put up is slagging some one off. He put up a decent thread about his car, why dont you take your own advice and f**k off to mig and post your useless coments on there!
love too twag...
so being realistic is being miserable is it.... meh
and not "every post" is slagging someone off (or again is the truth insulting to people). just the threads that need a bit of sprucing up :p
The Simps
17-10-06, 12:25 PM
As much as I agree with TWAG's comments above, you are very negative in most of your posts, if someone posts up a RR graph its bound to create some discussion. People with similar or higher specs achieving similar results etc. Unfortunately this discussion just turned into handbags at 10 paces.

If this thread was posted on MIG, Stuarts comments would have probably been removed and it would have been a more technical discussion looking more at the physicsetc involved. Its these more technical responses the reason why people use MIG and the reason the site is so large is because people want to learn. Anyone who has used MIG for any length of time and took the time to read posts properly they will no doubt come away with increased knowledge.

yeh course it does!!!!!!!!!!!!!:wtf:
its nothing like that! there is a good chance it good be around that figure!!
oh and i think you will find that was in fast car magazine
the first replies WERE on technical merit... jsut that technical merit was taken as a personal attack on said person and all his chums came to the rescue lol....
ie the power graphs is actuall a power torque, rpm and speed Vs Time... how anyone can "sell" that as a traditional power grapsh is beyond me as it offers no easy way to compare what your looking at with A.N.Others RR graphs..
as said i only highlighets the engineering truths etc... people didnt liek it and got handbaggy hence why it was kept on at... pfft sod it

17-10-06, 12:41 PM
I do personally tink the bhp figure isn't going to be too far out. For that spec I would expect 160-70bhp. The btb manifolds really are a piece of art. Its the torque figure that is very unlikely too me.
The idea of comparing the figures to TB's in reference to bhp is fair, but TB's don't seem to produce a great amount of torque but don't need to as they rev higher which results in a higher bhp anyway.
On my old XE engine which was built to produce torque it was producing 160 lbft. That amount of torque was the same if not more that is produced by most basic TB setups. But again, the spec was centered around improving torque.
To have a standard engine producing 173lbft seems unlikely.

I think most of the comments here are just the truth. I would have taken that 171bhp with a pinch of salt tbh. Sure that figure will inflate an SFi/XE owners ego but its just too good to be true IMO.
The relevance comes in when you ignore the estimated flywheel power & the guessed variables & purely look at the power at the wheels on that day (ie weather). Then come back to the same rollers (hopefully still as inaccurate) & produce another power run based on power at the wheels. If you have 3 bhp more than the 1st attempt, I would agree & I'm sure Stu would that you DO have 3bhp more than last time on.
Bragging about the manufacturer of the rollers will not help any cause. I know for certain that I would prefer the attitude of a modest RR operator than a boastfull money maker operator.
So, you have a benchmark figure that means little to any of us. Thanks for sharing it though.

your a f.u.c.k.i.n c.o.c.k like and id love to smash u! anyway what makes you think the rr is so inaccurate?? have you been there?? and why is my engine that i took out of a astra gte and installed in the nova MYSELF supposedly not the 170 claimed bhp?? i mean is that not possible or sumthing??

and i believe matthew YOU said both cars were "side by side"
see views honest truths and takes them as a personal attack....
yes i saw the green line was rpm, but if you as andyracer said, remove you head from your anus you'd notice how much of a swine it is to use the data from taht graph in an easy to use manner.... you can present as much data as you like on a grpah but if its incorrectly formatted etc then its as meaningless as getting a polar bear to count to ten.

whats the spec of the engine???
seems high bearing in mind the std EFI box is on there...
oh and mmmmm love the slanty kill yer engine RR lol
The sheer malice and envy underlying that post is frightning.
Id loose sleep over that :tard:
Come on its a forum dont post if you dont want people to discuss, good or bad. can't believe anyones surprised that a thread like this ends up focused on one thing.

I actually said, i used to have a nova sr in blue like yours that i missed but mine was as rotten as a pear and that yours seems rather tidy, i also said saracticly that ud stole my wheels. So when u have the correct information then get back to me. :thumb:
But at least i know why u were so funny with me, and thats all i care to know. Oh and i know a few things about u from various source but im sure ull know what im talking about ;)
