1.6 8v max power

[m.d.]

i keep seeing people on here say that they can get 150 bhp out of a 1.6 8v and i just want to see what these people are doing to get this sill power figure. it seems a little far fetched to be honnest but im here now to be proved wrong so please people fire away. :D

[Dan]

150 :) i will never quote that high ;)

[peester]

billy B+, cam then turbo or throttle bodies with dta/omex/whatever manag.
or carbs with bottom end work and prog.engine manag. and a little luck.

looking at ?2000-?3000 ish there though really. but a small block 8 valve running 150 has gotta be a std xe beater..? we'll find out won't we.
im sure dan's (admin) 1.6 8v on carbs matched or beat a 1/4 mile time set by std xe-ed nova at the rb/nl thrash @ pod..

My 1.6 8v was running just shy of 150bhp with shed loads of torque. I was only using 30mm chokes, but increasing to 32 or possibly 34 would have seen me well over 150bhp.

In the Novaload shoot out a few years ago, most 2.0 XE's ran mid 15's, with a few going below 15 seconds. I did the 1/4 in 15.18, CP's 1.6 8v eventually clocked 15.08, and now Dan is around 14.92.

More importantly, at Trax, I was quicker than all of the 1.6 or 2.0 XE's and all of the LET's with the exception of one 250bhp LET, which only passed coz I backed off after about 5 laps. It shows that a well balanced car with reasonable horse power can be quicker than a nose heavy car with lots of power.

Last year there was a 1.6 8v on carbs running in the toyo tyres series that was around the 180bhp mark, quite peaky, but thats all you need for track use.

There also should be another high horse power 1.6 8v bursting onto the novaload seen very soon. :wink:

My 1.6 8v is currently under construction and if i hit 150bhp i'll be a happy man, i think 140bhp is more realistic though. still gona mova well though, no need for a 2lt

Lets hope it doesn't literally burst ;)

[Stuart]

you dont want a 1.6, stick a smaller lump in ;)

[rysmee]

Dan and MC, are you going to be running yours up the strip at pv this weekend?
need to see how mine gets on against others similar, hoping for low 15's but we''ll see.

[Stuart]

mark has not got a nova anymore lol

Just had a look at your feature. Very nice car. 1.6 8v on throttle bodies. Will be intresting to see the comparison between tb's and carbs on the 1.6 engine.

which rolls back to depending where you have your r/r done in the first place as i run heaviest of the 3 and only quote 133lbft and 142bhp.

I wont be running mine as my times cant get any more common than 5 runs within 0.05 of a sec (5 times out of 7 attempts a year apart). Next year might show some lower times tho hopefully, even tho the engine wont be touched.

Lets hope rysmee puts in some good times to aim for :D [/quote]

[Ben]

Is BigRuss still going up?

[m.d.]

some good replys there.
im sending my bottom end away to be lightened and ballenced but ive been told that there is very little if nothing that can be done to the crank rods and pistons to lighten them. they can be ballenced a little but nothing that will be noticeable. the flywheel on the other hand will need lightening and ballencing but not by much.

im hoping to get a new exhaust system as ive ben told that my 2" system is now resttricting the engine and that a 2 1/4" would allow a few mote horses.

when ive finally put the thing all back togeather im hoping for 160-170 bhp as im getting 155 at the mo with a smokey standard bottom end :?
does this sound too much for a 2.0 8v :?:

[Jim]

Are you running twin 45's on your 2.0 8v?

Jim

Sigh...If I had a pound for every time you'd said that I'd have been able to afford a Diff by now ;)

Jim

yup, and oh do they bark :twisted:

[Barn]

Is BigRuss still going up?
no mate, he can't make the show

I was going up with him. He had his car back late and didnt have time to get the engine in, plumbed up etc before the show.

his car is f ucking awesome in all fairness

[BigRuss]

Yeah, no way the car would have been ready for today, I got it back from the bodyshop two weeks later than promised :cry: :cry:

Thanks for the comment Barney, You are one of only three people from this site that have actually seen the car in the flesh.

Getting back to the original topic, My 1.6 8v when originally dyno'd was kicking out 162bhp. It is the most powerfull one that Martin Bowyer (Bowyer Developments) ever built and has one two rallies outright. I am making enquiries at the moment to see if I can get any more power out of it but so far three engine builders (Bowyer, JRE + Rushspeed) all say no, it's just about on the limit. I'm running Cossie forged pistons, Enem cam, head and solid lifters with twin 45's and an MBE management system, see My profile for full details.

I'll probably have to get it topped and tailed at the end of this season as it will have done about 800 competitive miles by then and could prob do with a strip down and check/re-build.

So basically I know that 150bhp is achievable, but 180bhp definately is not :o :o .

[m.d.]

so you have spent a fair few quid on the engine then to get it above 150 bhp then

[BigRuss]

You could say that, If You wanted one the same as mine built by the same guy You'd be parting with just over ?4500 for the engine complete with 45's, paddle clutch, MBE Management and Tony law exhaust manifold and system.

[m.d.]

:o thats a hell of a lot to spend on an 8v lump. but i spose if you want to stay in the same class you nedd to keep the standard block and head dont you.

do you not ever think that your money would have been better spent on a 1.6 16v or even a 2.0 16v

[NovaNeil]

You 150bhp boys..... Tut Tut Tut. Get yourself a blower :wink: 181bhp mines been dyno'd at. 8) :D But you all say im cheating....... :twisted:

Within the next two months im going for the big 200.... which... as far as I know has never been achieved before with this engine. I don't care what boost is needed to get it. It WILL get it! :D

Would it be possible to run 45's on the 1.6 8v??? I know it would over fuel like a bitch, but with a mega lumpy cam surely that would make 165-175bhp? Not very practical..... but mad all the same.

Neil

[Dan]

neil he does run 45's and yes you are a cheat :wink:

[S_Gault]

neil- 45s are a must on a good! 1600.

I even run them on competition 1400s which run solid followers.

160 is acheiveable very easily if you know what you are doing on them.

its also possible to get 200-220 under the 1600cc rule limit but it all depends on the rules.

if you want i can explian more.

Steven

[Alex]

do you not ever think that your money would have been better spent on a a 2.0 16v

YAWN
At PV we were searching for all the smaller engined cars as the valvers were in 99% of cars there.

[Will]

seriously if i had taken a mate there he would have assumed 2.0 16v blocks were standard issue in novas........ every nova had one!

[BigRuss]

If I had built My car simply for straight line speed I would have put a 2.0 16v in it no problem, it is not difficult or expensive. But it is a rally car, and I can honestly say that I have never been beaten by any 2.0 16v Nova on a single stage at any venue 8)

I'm doing a rally on the w/end and there is a 2.0 16v nova entered also, it's worth noting that He is seeded 8 cars behind Me which means even the organisers don't expect him to beat me either 8) 8)

[Stuart]

what, where how who??!!!!!


:D

than again i couldbe a bad luck omen as you rolled her at the last one i attended lol

ps bonnet ;)

[HEVY-nova]

"if you want i can explian more."

yes please

[Funkdocta]

What's 150BHP roughly at the wheels? I remember reading on here a while back that r/r people up the results making the customers happier etc etc. this makes sense and often I feel this is what they've done to me but other times I can't stop smilin when I toe ma car - my results were 112BHP@wheels@5900RPM but i'm still running my bloody semi-standard ECU (tweaked throttle body and air flo)! everything else is done though, lightnin blncin, re ground crank, cam, skim, biger bore, 4-1 mani, mangex stainless (is that 2 1/4 thick or 2in?) Is this possible or have I been mugged off?

You compare on 1/4 mile times but surely there's alot of variation in this, (tire, track temps, air temp/humid, driver skills, .... my standard clutch :( ???

I know I should look at the fact i'm happy with the performance of my vehic but i'd like some solid figures that everyone can trust!

[Dan]

i quote 113@wheels/142@fly, thats with a high compression 1650, lightened balanced blah blah, big valve head with ast2 cam and forties etc etc. Compared to russ's bowyer motor with 162bhp@fly i would say that was fairly believable within any realms you could call comparible. But again unfort you hit nail on the head. There is no dead accurate 100% figure, just a guide as your mate might go elsewhere and claim more but have a slightly slower car. Also dont foget torque, bhp is all fine and dandy but the torque does have a large part to play.

here's my graph that is for reference each time i go back to the same place so i can compare (was spot on same 8mths after this was done)

[S_Gault]

lets just say it entails a different crank and a lot of work.

dyno sheets to prove it.

Steven

[rodgerq]

wasnt the grp A gsi 150 brake with the OE inlet?

rodgerq

[benji]

and a standardish head (no bigger valves)

[rodgerq]

yeah thats right. its all in the build manual. a great book
