I dont know if we are done... but Husam which happens to be a member here SMS Tuner called me to tell me he is aiming for 25 psi and arround 700 whp with a built 3.5 engin and a greddy TT and I GAVE HIM THE GREEN LIGHT.
Do you think we can? well sit tight and watch and we shale see.. I will keep u posted and pics and vid. of the run for sure

 

Hi Ali,
It is going to be some times the week after next week so i dont know if you can hold your breath that long .

 

Bump for a motivation..... hehehe

 

25 psi is way past those turbos efficiency range. If your tuner doesnt know that, I have no comment. Good luck increasing power, your car is already a beast.

 

I'm sure he does but dont u think it will hold at least for a dyno run just for the hell of the #?

 

with the greddy kit, anything past 18 psi it just falls on its face picking up about 5-8 hp psi and blowing A LOT of hot air...


it will be knocking like crazy, but good luck...

 

what, honestly, would be the point of that? if you can only make it one time on the dyno...what does it prove?

 

thanx for the feed back audible... we will surly keep that in mind..
and thats y i posted this here not for a show off but for safty reasons so far u and alberto dont recomend it and if it goes this way we will have to think twice befor doing it..

 

The point will be experimenting just like all what we know or at least most of us on this forum know is because of the sponsers or other people experimented on thier cars and gave us back the feed back...
and having a big # on a dyno sheet heheheh for sure

 

The experiment has already been done ... the results weren't very good ... I wouldn't waste a motor trying it ...

 

i think we pretty much know what greddy kits do at 25psi... but, if it floats your boat, go for it!

 

that's not how it works - there are things the turbos can do and there are things the turbos can't do. one of the things they can't do is make 25psi efficiently on a 3.5L motor... you can't force it to do something efficiently for one dyno run with a magic wand like some kind of wizard lol merlin.


btw half of your signature is spelled incorrectly (I'm not sure if english is your first language or not because of your location but I thought you might like to know.) denso not denson, fuel not fule, wideband not whideband, octane not octan.

 

OK,
Just to clear things up. we are going to take the car to the Dyno and do another session of tuning to see how much more power can we make this time considering the fact we were really Conservative the first time as it was our first attempt back then we may increase the boost a little over 18 psi. but i thank you all for the advices as we learned a lot from all of your experiences. we will keep you updated.

 

thanx for the feed back...
and about english u r right its not my first sorry for the mistakes and i'll try to be more carful spelling the words will fix the sign. later on.

 

WHAT 25PSI Ali, all what i can say that you are getting completely CRAZY....
what you have right know is more than enough. not to mention the weather we have!!! 50C it's already killing the power. Any way good luck

 

that we can be like the supra owners

 

all i can tell u is stay tuned and i shal update u soon...

 

I beg to differ... I have seen power increases above 18 PSI on a VQ35DE engine running the Greddy kit. If I recall correctly we saw power increases up to 22PSI, maybe even higher, but at that point the system was simply not giving any more. ( I stand corrected we were running the 20G upgraded turbos, not the normal 18G's)

I am sure it depends on the tuner & how well the engine was assembled.
Good luck with whatever you do. I am sure your tuner will notice when he is not getting any more power and drop it a notch for safety.
