gearbox was having issues to start with but after we sprayed water on the trans cooler started playing the game again, 521rwhp on 23psi and we have maxed out 1000cc injectors and going by the amount of rubber all over the dyno room and my car we are loosing some through the tires and the rest through the convertor and possibly gearbox. to max out 1000cc injectors with e85 we should technically be making around 750hp at the flywheel. lets just say that on the road it is insane

madness! nice sneeze afterwards aswell

also makes power all the way to new revcut of 8750rpm

 

Hell yeah, nice work mate!

Wwwuuuuusssssss-tutututututu... :D

I was right! It did make this sound! :D

 

Makes an absolute wicked sound mate! Love the Dyno lift on the 1st Vid! :yes:

 

Josh :cool:

You still on a stock motor yeah?

 

An my guess was only 11.1kw off :)

yeh still stock bottom end, not to worried about it can make plently more power on it yet. I'm more worried about the standard gearbox but it is going strong so far. i will run it how it is and then probably make a 4 point cage next year for it so can run deep into the 10's and eventually a 9.

And mine was 11hp, I win.

 

The joys of working on a dyno.

love the strength the jz bottom ends in standard form. think the rb30's rod's don't like going much past 380rwkw from what i've heard. wouldn't be to much left in the turbo now?

 

and trev that's cheating :P lol kidding. pretty happy with my guess considering i've never had anything to do with tuning car's or even owned a tuned car. actually now i think of it i aint even been in a dyno tuned car :(

this think is killer love it

 

and JZs are the best engine ever theres people who have made 1000+HP with a stock bottom end might not last long but it can be done

yeh i do believe you were the closest guess, id love to tune this thing with a standard convertor with lock up to see what power its really making. i just took it for a drive while the road is dry before it rains again and 80kmh in top gear turns straight to smoke and rev limiter i really think i have got to enough power for a street car.

to give you an idea it had 450rwhp on bp 98 with 19psi and 15 degress of timing, now is 23psi and 28 degrees of timing and just hits maxduty on the 1000cc injectors. so what power it really makes is anyones guess, will be interesting to what mph it runs.

turbo still has at least 10psi left in it, its pretty much the same turbo shane 1jz747 used to run, which he used to run 37psi and 100hp of nos on a standard engine. he had the same problem with convertor not giving a true reading on dyno but going by the mph he was making alot of power.

I have seen 1j bottom ends go bang from just a boost increase, even though it has an aftermarket ecu and e85 I wouldn't push it any further.

yeh were not going to push it any further for now just enjoy it how it is, we had the knock box on it and not any hint of detination. we went up 7 degrees to start with then added 2 more at a time and when we got to 28 degrees even though we hadnt got to knock point we thought it was plenty so left it there. the way i drive it would preffer safer over another 20hp

i just ordered a set of koni adjustable shocks for the rear to try and stop it squating so hard, but am unsure if i will need a heavier spring to suit. i already have corona springs in the back which are 200 pound instead of the standard 185 pound spring rate. I'm not sure if i go a heavier spring if i will get the bump or bounce kind of problem. anyone a suspension guru?
