Went to Dastek on friday, only to achieve 315bhp & 275lb/torque.

I was expecting to make around the TSL(330/333) package mark, or even higher as with the money saved on the package route, i opted for Harveys headers #2.

Setup:
Full Afterburner decat exhaust, simota panel filter, walbro fuel pump, ported & wrapped headers and up-pipe.

High ambient temps?

you have had a remap with those mods haven't you?

Don't know what its like upi new you, but its 30 degrees down here in kent!
I'd say that those are pretty impressive fiqures for such a hot day.

i was at dastek last week and lost a fair bit from the last time, every car was the same, at least 15 bhp down, all down to very hot air temp i think, also has it been mapped?

Dastek has sensationally good cooling and the dyno compensates for the temperature. 340 BHP at Dastek is typically induction, FMIC, TD05, tubular headers, remap territory for example, so 333 isn't a walk in the park on this (realistic IMHO) dyno.

My car did 20 BHP less and 60 lbft less than Dyno Dynamics in the same spec running at Dastek.

I believe the Dastek figures personally and think your result is reasonable, the turbo you have on there is tiny, too many wild claim dyno figures about.

Does it feel fast??

Does it do what you want of it??

WHY oh WHY all this childish geeky infatuation with BHP???

BHP varies on a daily basis, so whats the friggin point of a RR??

OK, OK, OK, it gets a bunch of billy-no-mates together to massage each others egos and get-off on paper graphs ................... but, is that REALLY what life is all about??

It's been mapped by AndyF.

It wasn't overly hot in Dalgety Bay (nr. Fife), i think 21 degrees.

Apparently was holding 1.35bar boost.

Just a bit miffed by the torque, thought it would be loads more than that. Certainly feels it. I just wandered if the exhaust was letting it down being 2.5".

pslewis

If it feels it - isn't that enough???

The exhaust isn't letting the car down ........ I'll give you 3 guesses who is!!!

Pete

GazTheHat

That's interesting to know, thanks. I just wandered if something was wrong. Or i'd chosen the wrong components or something. My paranoid little mind at work

pslewis

Please stop the world NOW .... I wish to get off!!

Shut up Pete you fool. I was asking a legitimate question. I didn't follow the crowd and get a package, but opted for my own route. Having spent all that money and "thinking" it was down on performance, i wasn't happy.

It's got f-all to do with massaging ego's or the like or bragging rights. I don't go to shows/meets or the like (but i might sometime) so can't show it off. Having spent all the money and reading all about upgrades, modification routes etc, i wanted to see in figures what it had achieved.

Go correct someones spelling or talk about cheap replacement parts in someone else's thread, if you've got nothing constructive to say.

Yes it drives superb, but i want more already!!

GazTheHat

So i've just got to wait for a cold day then and try again, that should be in July sometime then up here

And if you think you've got a loud car, you should hear their (Dastek) WRX. It is menacing!!

GazTheHat

Just jump now, no-one's stopping you

2.5 shouldn't be restriction at this power level.

Hi Floyd, still running the VF35..? How's it doing..?

If its not giving the figures you expect then the only thing to do is re-run it on the dyno at a later date, maybe it could be a bad batch of fuel? Heat soak etc.

If you still dont get the figures you are looking for you have a problem and I would take it to another RR just for a 3rd opinion before you start to look a possible problem, after all 15bhp down is only 5% out so could just be the RR.

So many factors can affect a brake dyno reading; gearbox oil temperature and tyre pressures for example... A brake is really only useful for comparisons but I wouldnt worry, myself.

Andy S.

Had mine on the Rollers on Saturday

Produced 326BHP and 344 ft/lbs torque
back in Febuary on a icy morning Produced 346bhp and 369ft/lbs


I would have said it was the heat of the day

ZEN Performance

Those will not matter a great deal on a dastek dyno, the loss of wheel power will be made up with increased losses being measured.

RB5_245

That's a good result at dastek, take it down south and run again if you want more power

Or AVA in paisly... you should make about 300 at the wheels there

Watch what you say Dave. You may upset some people.

I had the same issue last week at PowerStation. Only made 330/340 but I'll try again in the cooler weather.

Why does a hot day make any difference?

When mine was on a RR here in Germany they had 3 huge, massive, enormous fans blowing cold air directly onto the front of the car!!!

GazTheHat

Thanks for all the comments.

It seems that it was my lack of knowledge of rollers and that is a good figure (Paul did say that the PPP's only make 275-285 there), especially for Dastek.

AndyF is gonna time the accerleration on his lappy compared to a TSL mapped car, so that should be interesting.

GazTheHat

What about the next stage, say 20g Turbo and Induction kit, would a 3" be recommended then?

GazTheHat

I think i may go to Paisley some time then, one cold day for some exagerated figures then

Martin2005

Hi XRS,

what figures were you hoping for?


Martin

XRS

350/356 would have been nice

RB5_245

What me! Never! (where's the I'm an angel smilie)

Made me feel good the day my RB ran 185 at the wheels bog std (non PPP)
