should i be pleased with this or dissapointed? (im feeling the later at the moment!)

finally got the P1, TEK 3'D last tueday (by pat @ xtreme scoobies)
then got the car on ENGINE ADVANTAGES rolling road on the sat

spec:
k&n induction
HKS FMIC
WALBRO 255 PUMP
sx fuel reg
unequal length headers
H&S DOWNPIPE
ninja centre
ninja backbox
TEK 3 remap

i was hopeing for more like 330BHP

what does anyone think? should i get it on another set of rollers just to be sure?

any input would be great cheers

so you fitted a fmic and a decat and wanted 330 bhp?

optimistc I would say.

change the turbo as well as a minimum but try to have a look through the projects section at the numerous ways of attaining 300+ bhp, theres a lot more bits involved and I believe that the cheapest method so far has come in at just over £2k

what turbos are on a P1??

RoRu

VF 28 i think.

What power/torque do you make at 2300rpm?

Dark Blue Mark

It is a VF28 so 330 would really be on its limits.

I imagine its nice to drive, which I think is what Ali is hinting at. VF28 does spool nicely.

Your turbo is limiting you, and then possibly some 550's if you do change the turbo. Id say all your other bits are well chosen to accomodate a bigger unit.

PS - dont get hung up on RR figures, they vary massively. If you did a berfore and after, that would be more relevant.

That does sound a bit low to me, especially with a FMIC fitted. My STI5 Type R (i.e exactly the same engine as a P1) with standard TMIC has GGR/K&N induction kit, magnex de-cat downpipe, H&S centre/backbox, PFR7B plugs and Tek3 by Bob Rawle.

It made 320.7bhp/305lbs/ft on the rollers at WRC Technologies about 3 weeks ago.

he has only gained around 35 horses as the p1 starts at 276bhp with them mods i would be slightly annoyed but if they say turbo is holding you back try a tdo5/6

Iwan

Forgot to add, Pickle's P1 has a FMIC/Tek3 and that made about 350bhp on the rollers at WRC Technologies the same day mine was on. Not sure what else he's had done to his though. Another Tek3'd P1 with standard TMIC that was there on the same day made 306bhp.

I like the way you hid the lag and dodgy low RPM figures with the baseball cap

Iwan

Good one.

As soon as we'd done the first dyno run, the bloke took one look at the plot and asked me if Bob Rawle had mapped it. 8)

Dark Blue Mark

Hmm, different mappers

Again, dont get *too* hung up on RR figures - how does the car feel? Can you compare it with someone with similar mods? What does the graph look like? What sort of cooling did the RR have etc???

MB

Dark Blue Mark

You could take it to PE if you want a bigger figure

MB (being unusually contraversial today )

flatty_scooby

graph had nice smooth curve, car does now feel awsome to drive compared to standard thats why i was slightly shocked at readings,

cooling wise they had one big fan, but the bonnet was up so the k&n wasnt getting its usual forced air feed from my second mini scoop on the bonnet!

HOUSEQUAKE

I can share your concerns.

I de-catted my Type R, fitted lightened pulleys and had a (conservative) re-map by AndyF. My car feels much, much better and if I 'clog it' it feels like I might take off BUT, on a rr day at Well lane I got figures of 307BHP and 260 something torque

I was dismayed because I expected around 320 BHP, but what everyone said I shold be more concerned about was how low the torque was in respect of the BHP figures.

(Most cars get a torque figure slightly less than the BHP eg. 310BHP:307torque)

Do you know the car was actually making 276bhp before on those rollers? It's entirely possible you've gained a lot more (or less) than you think if you're comparing a "book" figure with a RR result.

Whilst Mark was stirring things slightly, there is a lot of truth in the comment that you could get noticeably higher figures on a different day on different rollers. For instance TEK + exhaust bugeye WRXs tend to make ~280bhp at PE, more like low 260s at powerstation. Doesn't mean that the cars are any quicker if you take them to PE to get the higher figure!

XS-Home

From various RR's attended you'll definately get +- 20 either way; though prior to people going to a RR day, its how it drives on the road that is important. Along with a safe map....

And of course just because someone achieves 330 with the same mods you have, the cars will not be identical, even direct from the factory we have seen a standard WRX with 250 bhp versus the claimed 225.

flatty_scooby

i spose at the end of the day the car seems to pull and pull and pull, and has so much more grunt than it did standard, and it keeps puttin a smile on my face every time i drive it , and also the main thing ,no DET on normal fuel!so is running much safer.
think i will try it on another RR and see what it makes, just to take an average!

Why to 2 totally standard cars from the factory make different power? Its the way the car has been put together and you could be lucky and get the good one!

The same goes for mods. Some people slap the 'ingredients' on and are lucky and others don't get the same results. Not all de-cats are good, not all headers are good, not all mappers are the same as is said before. Were your headers ported before fitment? Do you have a turbo induction hose? What sort of piping is on the FMIC - how many joins are there?
