Well fellow turboforders its that time again, opening day at the track at least for me any ways.
(Mid Michigan Motorplex, for anybody who has not been to this track it's great)
Well last fall saw my XR7 in a little bit of trouble, all over the place on the mph through the 1/4. Did a little research (search button on Nato and TF) My cam timing was way off and the car was running way rich. Fixed the cam timing couple of weeks ago. Car runs so much better.
Current Mods to 86 XR7:
Junkyard 85.5 motor w/ 160k, 147 compression
88tc 5speed w/spec III clutch, and pressure plate (its like a switch)
3" downpipe and exhaust Bobs elbow
LA3 and Big Vam with homemade CAI (thank you home depot
gillis valve, boost gauge, Bailey BPV
big fuel pump, APR with gauge
total tuneup with the motorcraft stuff
New cooling system w/180 stat, new electric fan with manual switch.
GN intercooler without scoop for the moment
stock 7.5 rear end (but it was hooked up to a 18.0 car until I got it. (posi works fine)
SMC alky injection with the .07 jet w/80psi
Recentley hookedup LM-1 (best piece of equipment I have ever bought!!!!
Took the car for a drive with a buddy holding the LM1, the car was so rich at 20psi w/ alky, 15 degrees base timing, 44fp
10.0 afr..... all the way through 4th gear. I turned up the boost to 22psi, (gillis maxed, but I ordered the high pressure spring) that got me 10.5 all the way through 4th. Next I turned the fuel pressure all the way down to 38psi, finally got the AFR 11.8. The car runs so much better. I'm shooting for 25psi and maybe a little more timing. Will need to change to cooler plug though. This four banger is really starting to go now :-)
Future mods, (within a month) new 105amp altinator, GN IC scoop, drag radials, new brakes (one of my caliper is setup) more tuning with the LM1
Travis
I'm having fun are you????
P.S. this damn car atleast has to match my 02 Z28 (stock)in the 1/4 13.30 @ 108 2.1 60'
At least in ET, it will not MPH like the LS1
Then my second post.......
Some more tuning questions.....
I installed some colder plugs... autolite 103
The car runs good on the colder plug, but definately have to let it warm up first. Got the gillis high pressure spring. Watch out with that spring. First time I punched it in 2nd buried the 30psi boost gauge. That was the first time I ever heard detination WOW. Fast as hell for 2 seconds. Any ways got the boost under control. 24-25psi through a GN IC feels great. My base timing is 14-15 with spout out. I have KS plug in until I see my mph at the track in a couple of weeks. Better do over 100mph. I got almost 97mph on 20psi with C3 last year. Over all the car runs great.
The LM1 shows my afr 12.0 most of the way across the rev range 2k-5.5k. I'm runing with 39psi of fp w/vacuum line off. I cannot raise the boost any higher with the T3, hell I pretty much past the operating window right now. I had to go more boost, my afr was way low on 22psi like 11.8 with 38psi of fp. I tryed 36-37psi but the car would not idle well.
My question is this. My SMC alky kit is providing alot of intake cooling and additional fuel. My AF looks great, but just because it is does not mean I'm not detinating. What to you guys think on base ignition time. I'm willing to pull the KS at the track after I see my mph.

Going for max performance on pump fuel, stock turbo, stock injectors, stock head(160k jy motor).
I already see a bigger turbo in my near future. As I can run more base fuel pressure and a bigger jet on the SMC kit.
