Getting very lean up top and you didnt even go to red line . Looks a little un- safe , Dyno only goes to a little passed 5900rpm and your above 12 to 1 A/F

 

True,

Actually the rpms read 200 rpm low so itr went to 6100, even so I had AAM flash my redline <down> for a while for safety

Thats the reason why I am not on 9 psi Pulley anymore.
Need a better fuelsolution for "9psi" Pully.
Likely going with fuel return This summer ,so I can go back to 9 psi pully and feel safer about it.

 

Dude, WAY unsafe!! Looks like your out of injector or fuel pump..Go with 440cc's and a return system and a UTEC over that reflash..We just did a procharged car the other day with a UTEC and stock exhaust that made 350whp and stayed in the low 11's A/F..

 

Guys, I am no longer on 9 psi Pulley.
So I am not running lean anymore.


Low to mid 11's except at redline of ( back up to) 6600 rpm which is 12.0, all others including 6500 are in 11's.

With my 7 psi Pulley

Hey guys Im not here much more on the G forums...

I just picked up an ATI (used) its been about a month or 2. I love every minute of it. Running RC440cc, with Greddy EU got it tuned by Shawn at Churches he as usual did a great job. I had a bad exhuast leak when we did the run though so I might go back for a check up Saturday.

7.5lbs of boost I put down 382hp 322tq. I know my tq numbers came up since i fixed the leak I dont know about the hp though.

Im having a lot of problems with my big cog belt being loose though. Anyone got any tips. Its a brand new belt but its just too loose. Any help would be great.

 

If the belt isnt slipping at all, then you should be fine.

 

It slipped on the Dyno we fixed it and its been fine i havent felt it slopp on the road but who knows.... Also what you guys doing about filers. That screen is pointless unless you're worried about sucking up a bird.


Sorry if im going off topic but this board seem to be the only ones who help and know

 

what other mods you got bro?

on the 7 lb pulley i hit 9.6 psi of boost acording to the dyno and my defi gauge

 

I have motordyne 1/2" spacer, test pipes, Borla, Greddy EU, Rc440cc...

Im re-dynoing Saturday I think I might be up to like 350tq.

 

If you put the 44 tooth drive cog wheel the blower will make between 15-18psi. The ATI procharger has allot more in it than most people think.
