what power do you think this will be running?

[ianglanister]

nova 2L redtop
ported and polished,chiped,4in to 1 maniofold,lightend fly wheels with a sports clutch and its got cams off a c20let with a polished c20let throttle boddie
cheers for any help

[Rich]

c20let cams??? would of thought it would lose power

[ben doodar]

if you put xe cams in a LET im sure itl give it a bit extra power, not to sure the other way round tho

[blue_peg_16v]

you will loose power with let cams with xe cams in it id say 170-180 depends on the extent of the head work

[meritlover]

iam not guessing until i have seen what tune its running. i think the let cams wil lhave very little over lap, so i dont think it will make good peak power.
you basically have a polished head with a manifold. whilst the flywheel will reduce the inertia and help with acceleration, i would not expect as big a jump as 180hp. but it is not an easy thing to guess

[blue_peg_16v]

i had a mate who had a standard valver with a chipped ecu and a blydenstien head on it with the usual exhaust and filter and that pulled 183 on the rolling road but that head was the dogs which is why i estimated 170-180

[Stuart]

I would say on an HONEST RR that engine will make standard book power unless its had a FULL rebult recently. At best an XE is going to be 15 years old, and thats a shed load of wear/power lost through that time.

oh and add in the LET cams losing you power lol

[SRimon]

I reckon 165 tops

[craig green]

I'd be pleasantly surprised if that makes over 'book' figures tbh.

You cant really make much gains with the 'SFi'/motronic still in place & chips, if a good one help driveability & mid range torque if at all.

The other factor to account for is what RR you get the figures from. That alone could make the outcome seem optimistic.

183hp from a port/polished head?

Thats all you get from a 2K throttle body kit from SBD.

[Adam]

Ianglanister-I agree with Stu, 150-160 is a good estimate.
Fly and clutch wont change power.

The only real things that will help are the head and 4-1(assuming thats not just the standard 4-2-1 that all xe's have)

[craig green]

Only way to know for sure is put it on the rollers. Also get a benchmark figure for a std SPi engined car too. Just to see roughly how accurate* the outcome is.

* somewhat of a contradiction.

[meritlover]

a comparison with the same dyno and a std engine is the best bet. dynos have a habit of being extremely accurate in their consistency, yet they differ somewhat from unit to unit with Hp figures. and dont come back and try and impress me with ATF figures. they are meaning less unless you took the time to remove the engine and strap it to an engine-dyno. lol

[craig green]

Aye. Std SPi @ wheels. Your LET cammed XE @ wheels.

[ianglanister]

its not actualy my car its someone i know and he said last night its running around 276bhp which i didnt think was right so i thought id ask u guys, thanks for the replies!! ian

[Adam]

Are you sure its not a chipped LET?

[ianglanister]

its not a turbo, u want me upload a few pics of the engine?

[Philsutton]

LMFAO its either a LET or someone is feeding some serious crap. If its a XE take the LET cams out and put standard ones back in.


To get that power out of a xe without nitrous it would have to rev to about 10k and have just as much money in it.

[Philsutton]

Thats a XE and will be making maybe 160bhp if he's lucky imo

[Adam]

LOL 276bhp

[ianglanister]

tell me bout it

[Philsutton]

indeed adam,

[Adam]

That van would fit inbetween those two bollards at the bottom :p

[Philsutton]

I bet I could get it between them yes, might lose some paint though lol.

Ah well another fail just in case.

[Jack]

No it wouldn't, and they're removable bollards ;)

And I'd also like to add a LMFAO @ 276bhp lol

[Nobby]

pmsl at this thread you hear people say "oh buts its chipped" my xe is chipped with a 4-2-1 manifold coscst head filter all that **** and its only just over book at 158bhp bloody kids!:roll:

[blue_peg_16v]

the figure was for kevin whithams green nova was recorded at a vauxhall performance car club rolling road day about 8 years ago, he only had the head done as at the rolling road day we had gone to before mine had pulled 179bhp and his only managed 163 and he had built my nova for me, both sets of figures were recorded on well lanes rollers in batley

[CP]

Someones pulling someone else's plonker. Anyone for a metric adjustable or a sky hook?lol

[craig green]

mine had pulled 179bhp and his only managed 163 and he had built my nova for me, both sets of figures were recorded on well lanes rollers in batley

Saying 'Well Lane' says it all really, however what it does prove is one was 16bhp over the other. Tyre pressures could account for half of that as could tracking issues, a shot gearbox amongst other factors......

[RJM25R]

Well lane = happy rollers!!!

[Adam]

Ive heard that too,Lol.

Guessing this is same car that just posted on the 1/4 mile thread?

Car-C20XE on r1 cArbs chiped ported and polished lightend and balenced fly wheel f28 box:) (267bhp) rolling road proven!
Tyres-Toyo Proxes T1S 195/45/16
Estimated car weight-Around 890kg- partially Stripped interior
Reaction-?
Time-11.9 @ 113.3 MPH
Run at- santapod raceway - last year!! was gr8 this year again!! with more mods mite be turbo and nitrous yet:):)

[16v_nova_16v]

hey that ian lad is on about my car it hasnt got c20let cams its a c20let costcast head the f***ing muppit lol and its got c20let injectors with wats listed he needs to get off here he has bined his nova for a 1.6 16v jap crap corrola on a h-reg witch been hand painted with black hammerite lmfao i thought this site was for ppl with novas lol n e ways pics will be up soon and once its got the turbo and nirtous on it shud be nice n fast!! i have rolling road papers here too!!! lets just say well over 200bhp

[Rich]

well over 200brake? how much it cost you to do roughly

hi all
there are some real bull **** figurs here.
most C20xe's are not 150bhp,
a very healthy rebuilt engine would make that power or close
most would run about 130 if in ok condishion imo
adding a filter will make very little difference to power but will increase throttle responce
a 4-1 manafold will doing nothing but lose touqe.
a 300bhp xe run a 2" bore 4 to 2 to 1 manafold which would come as fair back as the b piller on a nova.
cams on standerd pistion will do nothing
most other mods need a standalone mangement to see the improvement
a standalone mangement and ground b or c manafold NOT 4-1 will see about 170ishbhp alone. on a healthy engine
flywheel will give it better pick up and rev up faster. balance will help it do this and stop it shaking at high revs


i'm going to stop
RICH
to see 200 if all parts are new you'll looking at 5000.

[RS SHORTIE]

Where are the R1 carbs?

if you say you can get well over 200 bhp from your xe with just a coscast head (that will give no power gain in standard form) and a set of let injectors?

then i think there will be alot of lads on here that will be well pissed off after spending ??? on carbs/bodies!! fpmsl

[meritlover]

a LET head? surely with a LOWER compression ratio? and over sized injectors running what management? just a chip? hmm

Carbs and chipped? what did you chip? the std ecu to control the timing? this cannot make good power, you would have to install an AFM and use the std sensors with the ECU to give 3d timing which would be almost vital to make anywhere near the power your making on a relativley std engine.

[burgo]

a LET head? surely with a LOWER compression ratio? and over sized injectors running what management? just a chip? hmmlet and xe heads are the same. the compression drop is in the rods and pistons
