After 5 years.First dyno and test drive (video)

[Harnasiu]

Hi
It's been a long time ( 5 years) since I could supra move forward.

Turbo it's GT 4088 A/R 0.81 .
Mods:
port/ polished head,three angle valve job,2mm HG,Ron R. FFIM,clevite 77 bearings,Probe pistons,ARP studs, eagle rods,clutch rps3200,Walbro 255, RC 750cc,Custom full 4inch exhaust,Innovate LC-1 , all controlled by AEM

First dyno 380rwhp/11psi on pump gas. Im waiting for Bc 272 and spring than we can push it to 30psi.

Nice build... Which AEM standalone did you go with?

Of course.

Nice torque curve! Roughly 357 ft-lbs by my conversion, but starts nice and early... Looking forward to the future with this one.

New dyno. 500rwhp/15psi Pump gas

wow it never peaks, im assuming this graph is with the bc272 cams? also is this a journal bearing 4088?

I myself am impressed by the power.Turbo is without journal bearing. Yes i dynoed supra with bc272. There is a very large difference in stock vs 272 cams !
Waiting for biger tires and after that im increase boost to 30 psi. Im looking 700rwhp.

You don't have enough fuel pump for 30psi. Great numbers though.

Yeah, I know. At this time,i have single walbro255 but there is a no problem to put one more walbro.

 

[ricoboost]

instead of using a second walbro 255 you should use only 1x walbro 400 its more reliable that way

 

[suprahero]

It might be, but I've used two walbro's for the last five years with zero problems.

 

[ricoboost]

you might be lucky or me unlucky but i didnt do more thant a couple month and this is juste 30$ more instead of paying like 110 for a second new one

I feel like a bit of a cheap asshole asking for this, but any chance I could take a look at your AEM map? I'm interested in comparing timing curves - My last tune was on a dying motor with a shitty turbo and my new set-up is pretty similar to yours (750 cc injectors/ffi/6065 turbo but no cams).

I understand if the answer is no...I know what a tune costs.

Nice power by the way. 500 whp on 15 psi is no joke. How is the idle with those cams?

 

[Enraged]

I'd like to see a timing map, simply to see if mine is even close to safe lol

 

[slowmedown]

nice indeed. now fix that windshield lol!
