I just got done installing my new pullies for my ATI Procharger. I took it for a spin and about **** myself. The power was amazing. I never knew that going from 7-8 psi to 9-10 psi would be so dramatic. It wrapped from 3000 to 7000 rpm so quickly, I almost forgot to shift. I just wanted to share. It was a huge pain. I had to pull my entire system out in order to get a puller on the pullies. While I was down there I also changed out my thermostat to the Nismo thermostat, I still don't see why they charge so much for that thing. The housing is identical. If they would just sell the actual thermostat it would be so much cheaper. It even has phillips screws holding in the thermostat, so it would be an easy swap. Ok, I am rambling now.

Sharif, I look forward to the Emanage Ultimate!!

Next projects are my own return fuel system, just waiting on the rails, 440cc injectors and a Walbro fuel pump, followed by another TS re-flash. When the plenum is off, I am going to install my Greddy catch can. I think I have too many things on my list. HP is addicting!!

 

Is that even safe with California gas? I just hope you're not detonating.

 

I have a lot of timing pulled and running the J&S Safeguard. I hope that is enough. I am also running a little richer, abot 11.0.

 

Plz help me trying to figure out a problem..how were you able to run this rich?

From your Mods list, you have the ATI FMU, ATI Aux pump plus stock pump inline plus stock injectors?


This is my exact set-up on fuel and my breathing Mods are close (Mods list in sig) just got 9 psi pulley yesterday at AAM, plus a re-flash/retune but we couldnt take advantge of an extended redline because at 6400 rpm the car was at 12.6..
According to AA stock injectors with ATI FMU were running out of fuel at this point.
They suggested, Walbro, emanage, 440 injectors plus their fuel system as a (very expensive) fix.

So in the reflash, my redline actually had to be lowered to 6400 rpm..

I wonder if injectors and a walbro will be enough to get me safe enough to extend redline atleast back up to stock.

Also I ran it 0-120mph sprint today and my EGT was up to approx 840/845 C , on 93 Octane, good Eastern Gas. (Usually at 700C during slightly elevated highway running, approx85 mph, or 570-600C during easy driving , 55 mph)

Subscribing.

Fred...

PS: So you are tuning with your J&S over a reflash.? any problems at all? Any detail you wish to share..
PS:#2 What were your power numbers on 91 Octane? I got 355 DynoJet rwhp on 93 octane, only a small improvemtn over my 7 psi #'s (even tho the car <does> feel stronger now and it <was> a hot day yesterday when these numbers were pulled )

 

Well, to start off, I have just ran a few test runs this evening , my A/F numbers were from me peeking at my AEM gauge a few times. I will get more exact numbers tomorrow when I can get a few runs in. I assume I will max out these injectors. That is why I am getting the fuel mod. I have all of the parts except the rails, they will be ordered on Tuesday. I had it on a Dynojet a few months ago and put down 350 WHP. I know I am giving up a lot of HP due to my timing. I was also pig rich, 10.5 at times. When I had it flashed the first time, I did not have the J&S installed. They pulled extra timing out above the standard ATI flash. I have the J&S only pulling 2 degrees above 5250 and pulling 0 with boost. When I get my new flash, I am going with the stock maps and plan on pulling timing with the J&S and hopefully the emanage ultimate.

As far as EGT, Mine has always been around 800-900 F cruising. If I am getting on it it gets up to 1250-1350 F. My probe is installed in the top of my test pipe. I have read that temps vary widely from car to car.

Walbro and injectors only without a return system will be good only to about 400-410 at the wheels. This is from Sharif and Charles, A.K.A. Phunk from CJ Motorsports. I was going to do that route, but got a good deal on a Fuel Pressure Regulator and some rails, so I am making my own return system.

 

Thanksf or the quick response:

temps I just converted your numbers to C.
Looks like your cruising temps are 100 C less, as is your (getting on it) temp (730 C).

I dont want to go any furtehr in power mods than my current pulley.

The chance at saving $1000 by not going with a fuel return system and just injectors and walbro is a tempting one..

They sure do vary, im hitting 1500 and change, when crusing at high rpm, say 3500-4000 not under boost. My probe is right after the manifold pre stock cat. Im thinking that the stock cat is acting like a big heatsink.

 

They will vary mainly due to location, if one is going to be installed it is sugegsted that it be installed no more than two inches from the block ie on the headers or exhaust manifold.

Subscribing...good stuff guys, finally some useful information...too bad I tagged a deer with my car yesterday morning! Monkey- good luck with your fuel system, I still have your info and maybe I'll get everything worked out someday! Palmer, I know the fuel system seems expensive but I'm with these guys, it is SUPERIOR to the unit we have.

 

Your thermocouple is downstream? wtf? It needs to be in the exhaust mani to be useful, and you really need a good egt signal if your pulling that much timing because less timing is going to give you high egt's!

 

mine is almost at the maniford. From what your saying (or im reading)It seems like the a double sided sword, high egts or higher risk of pre detonation?

 

I couldn't get the probe installed in the manifold, so the next best thing was as high up on the test pipes as I could get it. I realize this isn't the ideal place but it was what I had to work with. I have a few more runs under my belt and I have to say it still rocks. I do notice a leaning above 6000 RPM, I have not seen it go above 12.6. I am keeping myself limited on my runs, as I don't want to get too lean. I will be doing the fuel system this weekend.

palmer,
I think the injectors are maxing out as well, I cannot wait to get rid of this FMU. I am putting together my own fuel system. When all is said and done it should run about $600-$650. When I get it done I will do a write up and post a complete parts list.

I can't wait to get this thing running with more timing and more available fuel.
