This is my dyno with a gt3076r, 0.82 housing and stock cams, 1.3bar

Mine creeps into the high tens at wot too safe?

What would a 0.63 housing be like at the top end with stock cams at 1.3bar? Thinking of swapping from a 0.82 to get quicker spool

Sorted the pulley was bent ever so slightly, looks like someone has taken it off and bent it when they tried to hold it still through the holes

Currently got a torsen but wondering if the 3.7 would be better as it has more power now

I have a gt3076r 1jz with a 0.82 and full boost 1.3bar is at 3800rpm and pulls hard all the way to the redline 372whp dyno'd As you said a 0.63 would make boost instantly but will ultimately restrict top end power and be too twitchy for a street car? A guy over here has a 1jz which is a...

My hydrofan pulley has a little wobble when the engine is at idle is the pump on it's way out?

Max boost is hit at 4100rpm 1.3bar The torque line is the fainter line on the dyno printout 340ftlb @ 5100rpm (original post) Just found a garage locally that does 99 octane which contains 5% bio-ethanol worth using over shell vpower?

Appreciate all your input will just leave as is for now then and think about cams etc after the summer

If they are my only options then I don't think I want to go down the road of race fuel or meth, just want as much bhp on pump fuel as I can reliably get from my setup

So if I was running 102ron I could turn the boost up to 1.4-1.5bar? Is the reason that When I boost past 1.3 no more power is made because the ecu detects knock and pulls the timing Worth mentioning I found out shell vpower is 99ron over here

500bhp with a gt30r and stock engine?

What would stop it making more power past 1.3bar?

shell vpower 98ron best fuel you can get over here without travelling 60miles for bp 102ron

The engine is stock internally 540cc injectors gt3076r 0.82 housing Emanage blue 3" exhaust FMIC etc 1.3bar 372.5whp Just wondering why when turning the boost past 1.3bar no more power was made is that the wall for a stock lump with a gt30? Don't get me wrong it is very quick but I...

Bet your really pleased with those figures I only hit 372whp on a gt3076r bit gutted TBH I assume your turbo is gt35 size?

That was a good run when does boost come on strong 4k? 1jz? (can't see the vid on my phone)

Just fitted the apexi exhaust and its not that loud at all you could live with it on the motorway easily What I did notice was my car wouldn't hold 1.3 bar steady rather it would fluctuate 1.1-1.3bar you could hear the screamer pipe coming on and off any ideas why? As it didn't do this with...

did it drone on the motorway?

I thought the gt spec had stainless piping this has coated mild steel pipe
