Don't forget the M and the T+ :D

catons scooby 25 March 2008 11:47 PM

still unsure what it is andy, will let you know the outcome,

catons scooby 25 March 2008 11:49 PM

anyway, who is running a fp red, and how come your running the green dynamix? surely sticking 2bar in a fp green is pushing its limits,
(im still reading up on all this technical stuff so bare with,)

scoobyDAZZA 25 March 2008 11:55 PM

T+ ?????????

tell me more :D

2 bar is well within the greens limits mate.

catons scooby 26 March 2008 02:32 AM

so what is the max boost from this turbo, mate.

frayz 26 March 2008 06:54 AM

Im unsure of the max before it starts to become inefficient, however both FP and SM say that the green is more than capable of 30psi. Thats circa 2 and a smidge bar :)

Ive certainly seen 2.1bar from mine, however it was backed off out of mechanical sympathy for my stock rods lol.

How come the green ? - The first two rounds of Time Attack are at circuits that suit a more responsive and punchy turbo, hence the green. As it turns out, the top end response/power seems to be more that I anticipated aswell. :luxhello:

I will be testing the SM version of the Red though to see whether that is more suited to Silverstone and Snetterton because of the outright power advantages.

As Frayz said, the Green can cope with over 2 bar of boost and from what I have seen charge temps wise, it is not troubling my FMIC at that level.

had the T+ on my 2.5 sti 500/520 and very very little lag.

sorry fot slight hi-jak, but

am i being dumb in asking why boost would affect rods, thought rpm was a rod killer? or is it the torque it produces, just curious as if that the case i'll be putting rods in my 2.5 build

Andy.F 26 March 2008 09:57 AM

Its a combination, normally high rpm will fatigue rods and they will fracture in tension but you can also apply too much compression force to them and they will bend.
The compression force is a combination of rpm and torque.
FWIW I have ran my 321T at 2.4 bar on std rods but just for a very short while ie as long as it took to get a torque reading of nearly 600lbft :D

cookstar 26 March 2008 10:04 AM

600 :eek:

Having said that, the solid 1.7 bar on my stock STI topmount poses no ACT problem either. Even on the STI topmount im not seeing anything above 30 deg c :)

Austrian Impreza 26 March 2008 11:19 AM

Thatīs some good news!
So a SR55 or something like that will not be a problem to run with the TMIC!

this is my fp red power output

503bhp, 450lbft
uk turbo my99 sm built stage 2 engine, 2.5ltr, original heads and GEMS ecu

Austrian Impreza 26 March 2008 02:42 PM

On a 2.5l right?!
Impressing numbers anyways!

catons scooby 26 March 2008 02:52 PM

yep 2.5ltr

ImprezaGT2 26 March 2008 08:06 PM

What about the Frank 35 on a 2.5 Axis motor?
