What single turbo (s) you guys running?

[Jono FD3]

how are the others looking?? I thought that was the black sheep when I saw the compressor map..... & the figures were very hard to read on it as it was a thumbnail size image

:rolleyes::rolleyes::rolleyes::Giggle:Giggle you wish lol

your right lee :WaveBye gotta love these threads though haha:rollin
 
youd be hard pushed to make 650hp from a t88 at 1.2bar im not going to put a figure on it but it wont be any where near that the heat build up at higher boost levels on the t88 is an issue me and james willday both have expirience of this

[rbs14a]

how about the borg warner s475

[SiH]

470 seems a fair whack from a 35r - I\'d expect it to be more 420/430.

Is this American RWHP?

your right lee :WaveBye gotta love these threads though haha:rollin
 
Yeah they seem to be coming thick and fast at the moment:yes:Giggle

[rbs14a]

hope they dont turn up to pod or we\'ll have some serious competition :rollin

hello simon dont know about american rwhp sounds like american b*llocks though

[turbotoaster]

well that seems about right for 1.3bar, one guy on here made 400bhp on 0.9bar on a stock port.

so id imagine with 0.4bar more and a bigger port 470bhp is achievable Si....not rwhp of course lol

[turbotoaster]

what do you get for this turbo at 2bar.

its on a big streetport so dont know how you will put that into your equation

Compressor wheel - 74.68mm/100.07mm 100lbs/min
Turbine wheel - 83mm/74mm
Compressor inlet - 5" hose
Compressor outlet - 4.21 v band
Turbine Inlet - Divided TV91 (T6)
Turbine Outlet - 5" v band
a/r 1.10

Figures should be flywheel bhp.
Turbo toaster, That one comes out at 653
basicaly the calculation gives you a thearetical Max bhp.... basicaly using the maps to see the max flow rate at a given pressure ratio, then multiplying that by the 7.69bhp (rough rotary figure) per Lb of air flow produced by the turbo. but that doesn\'t mean the engine can flow that much so figures can be way out on the bigger stuff!

[rbs14a]

to be fair si col made 400hp on stock ports at 0.9 with the oldones touch on your ports you wont be far from mid to high 400s

[L18M]

ooh, i\'ll play along

T04E 57 trim or was it 60?
lets say 1 bar

so if this turbo has done 671flywheel bhp on 22.5psi of boost on a streetport what are your thoughts on that, his dyno is wrong or something else, this wasnt USA by the way

100lbs is 1000bhp in piston money or 769bhp in rotary, you saying we would need to run about 3bar to achieve that figure?

[Jono FD3]

comes out at 376bhp @1 bar

[lee mills]

Try this one T51 kai 1.4bar
