second coupe and second time to perfect touch!

booked in for the 20th of march the thursday before good friday!

cant wait what to find out what it is now and what it will be!

any wagers guys??

spec is:

helix organic clutch
3.8fpr
greddy profec b spec 2 boost controller
gt28rs 0.64
3" custom downpipe
3" custom exhaust (with restrictor to create back preasure)
3" decat
warlbro 255 fuel pump
pro alloy fmic
custom hard pipe kit
sip with cotton filter
hks bov


i think thats it

im hoping for around 350bhp
with 300-310 lb ft

whats the max on that spec people have experienced as i want the car for track and as a daily driver so it must be reliable.

There is a good indication of what PT will do. I reckon around 330 bhp with 300lb/ft.

i was hoping for that kinda hp figure now lol!

Well i think Kenno has a 0.64 aswell? at 320bhp? And 007 was 324 so you'll just need to wait and see.

Ross

what boost are you thinking of running?

i would say 330bhp as it is nearly the same as busa's!

kenno runs the RSR i believe

thinking of running 1.3 bar lo and 1.5 hi

Yep, i've got an RSR. 1.5bar on standard internals is for the brave.

PT's figures tend to be lower than most dynos

For comparison, you need to look at other cars that have been on PTs rollers.

My estimate is that the ATW figure for PT is about 15% lower than most other tuning houses (whether this makes PT 15% out or whether it makes all others 15% high is a matter for discussion)

My guess is that you'll see 320 - 330 bhp at PT with that setup. If you want pub figures, just take it somewhere else and you'll have 360 on the same day

and I agree - 1.5 bar on standard internals is asking for trouble - I bent a rod running 1.55 bar (on forged pistons)

i was running 1.5 bar and 3 pistons went, that was also with aquamist!

Other way round Nigel, the wheel figures on Dastek dynos are a fair bit higher than most places but the fly power is a little lower hence ending up with silly transmission losses of circa 5-10%.

I would be happy to run 1.5bar midrange but you must slowly drop this off to a sensible level by the time you have gone over 6k.

you're right Flea - I got it the wrong way round - PTs fly figures are low but wheel figures are about right.

I suppose you could take the view that fly figures are irrelevant, its what's at the wheels that counts. Therefore, PTs wheel figures are about the same as other dynos, but for some reason, the extrapolation for transmission losses gives lower estimated fly figures

My (amended) guess is that you should see about 300 - 320 at the wheels. At PT, this will equate to about 330 - 340 at the fly - at other dynos it would be around 360

Isnt it all dastek rollers that are like that?

Ross

hmm im gonna say 310-320 on PTs rollers

ohh and 290-300lb ft

I am going for 345bhp and 320ft/lb at max boost tested, which I think you might revise down to 1.4bar

(I am going to set my max at 1.4bar, only got std internals)

yes mark, but i wouldnt push 1.4 to the redline. tell rob to run 1.2 max to the redline for more safety.

Understood, thanks Rog
