Damn that 91 piss water really sucks then. I'm glad I drive an extra 5 miles to get 93. I would throw some meth injection into that.

i am not impressed by the 20g on the srt really looks like your car didnt hit full spool till almost 5000rpm my gt40 hit full boost at 4700 and that was 30psi.

prkersrt4tom · 03-17-2007, 11:36 PM

i dunno but i think he needs to turn up the boost. his afr is mid 11's looks like but i'm seeing people pushing 26-24 psi spike and 22-20 to redline. thats anywhere from 8-6 psi difference which i think would be huge especially since the 20g looks like it comes alive at these psi levels. Hopefully you can turn it up bro and see if it helps

SHrtShft-4 · 03-18-2007, 01:22 AM

I would have turned it up but for some reason it would wan to cut out around 20 to 21 psi. Fule cut or spark out. We couldnt figure it out. So this was the last run. On a safe conserv. tune. I would rather have been safe than sorry. I need to work out some knk then I will turn the boost up.

My highedt number of the day was a 348.

**kevinwarren240** · 03-18-2007, 01:42 AM

oh i have no doubt in my mind that this will make decent power say 430 with a 28 spike and 22 at redline. how does it spool on the street dynos are deceiving most times. I bet it feels super fast. congrats on the numbers i wanst trying to come off wrong. different is good most times.

SHrtShft-4 · 03-18-2007, 01:46 AM

It pulls pretty hard for 320. I like it! A mustang saw the aftermath of a 4th gear pull on the highway, on the way home.LOL

I just cant wait till I can turn the boost up.

My goals are 350 over 400 tq pump, 380ishhp on a race tune.

vcious · 03-18-2007, 10:17 AM

what are yuo using for boost control?

SHrtShft-4 · 03-18-2007, 10:47 AM

I was using a AEM TRU boost. I ended up buying a manual. SO know I use the manual.

vcious · 03-18-2007, 11:30 AM

what happend with the truboost? mbc's cause alot of spiking on these turbos for some reason. they hold better on just the wga and ebc's too(supposedly). i had an mbc on it would spike to 24 then fall to 20 before it even reached 4500rpm and stayed there till redline

. took off the mbc and modified the wga to hold higher boost. now goes to just under 24 very slowly backs off to just over 22 by redline

. full spool is about 3300-3500rpm. it spooled the same on the mbc. never tried an ebc, but others say it works just as good if not better. goin' back to the dyno next week to see if the hp came up. the butt dyno says yes. it pulls alot longer up top.

SHrtShft-4 · 03-18-2007, 04:47 PM

Thats why I changed but both were spiking. It like wew are have the same problem. Except my spike harder on the EBC than the Manual.

vcious · 03-18-2007, 07:48 PM

oh, well i won't even bother tryin' an ebc then. what are your other mods and pcm your usin'? just curious as to y its cuttin' out at higher boost.
