I know this kid who had a GT3071R on his SR with just some cams and a stock exhaust manifold. Rom tune of some kind and these are his numbers. Good numbers non the less on your set up. (PSI was at 16) He made some more at 18 but there is no dyno graph.

 

DAMN that is a smooth curve! Wow that thing looks like it spools nice, lots of area under the curve...me likes! That's actually right where I'd like to be boost/hp wise. I think the stock cams are really killing my top end power. Anyone agree?

 

good numbers. seen your video. looks good man

 

Cams would be my next upgrade for your list.Or save up and build the head with cams, springs, retainers, RAS's.Thats all ill probably do with mine, maybe a faster spooling turbo.But im only shooting for 300-350WHP.

 

Steve... you neeeeeeed cams....264 s2 + springs.... 375+ rwhp.... game over... BTW.. the other chart is of a 30r .82... notice it was tuned at our shop? It was running .9 bar.. but spooled later than yours.

Martin is correct, I keep thinking 300 WHP will be good for me.then i see something like this and im like Eh, whats another 100HP.But good luck with your none the less.

 

Martin, Glad you commented. I've got a question for you. I was abotu to make another thread about this but figured I'd post it up in here first. Yesterday on the way home I did a little bit of playing around on the highway. With the car on high boost it's overboosting in 3rd and 4th gear. I set the limiter at like 17.9lbs and when I roll onto it in 3rd or 4th it hits the limiter then reduces boost. When the limiter turns off the car overboosts again and then limits the boost again. It keeps doing this until I either shift to the next gear(where it does it again) or get frustrated and let out of it. It's a very noticable difference too, it actually feels like I'm backing off the throttle then back on. I figured it was something with the gain settings but I don't want to screw with anything you've set up. I figured I couldn't do too much damage by setting the limiter but after that I like to leave it how you set it up. Any thoughts? This was actually the first time I've done any longer, higher speed pulls in the car so this is the first I've noticed it. Anyone else who can help please let me know!

 

You are correct sounds like your gain is set a little to high. You can experiment with it on an open road by backing down the gain a little bit at a time in the gain mode. Until it holds boost and doesnt overboost.

 

DriftingDJ you're my hero! Thanks man, I'll go F around with that tonight or perhaps today on the way home from work.

 

I will be at XAT at 1:00 chillin with Martin till late if you need help. If you have a greddy profec b I can put in all the same gain settings I had with my 2540r.
