Finally Intercooled

I got a brand new LS1 maf off ebay dirt cheap. And I'd call any kind of obstruction in the middle of a maf sensor "bad". Any kind of a lip sticking into the air stream is enough to cause turbulence.

Well, this one was only $15.00, and at the time I was not sure how it would flow. I could file away most of the tab area, but I'll just wait till I find another unit. I believe I found a '97 LS1 calibration that you posted. I'll start with that.

All you have to do is copy the LS1 maf table into your pcm. Very easy.

Yeah, thanks for staying on my case about that. I pasted the '97 'vette calibration in, and it works fine "right out of the box." Drivability is excellent, throttle response in all ranges is better.

So even though I haven't redone the funky intake tubing, I just had to get it to the track. Traction became more of a problem than before, but that's the kind of problem I like. I had to keep the rpm's at about 1100-1200 off the line to get any traction at all (not an ideal launch).

Stock LS1 MAF, 2.0 in. pulley on S.C., reading 10 psi boost in IM., iced IC., D.R.'s

Test and Tune, Sept. 19, '07 (Bandimere Speedway) (Elev. 5860 ft., 75 deg. F.)

3) 14.115 @ 96.31, 2.076 60 ft.
This is good because I had the air filter, intake tubing, and muffler installed, and running about 75 lbs more weight in street trim.
4) 14.038 @ 97.05, 2.091 60 ft.
Without air filter and funky tubing, muffler still on.
5) 14.081 @ 97.69, 2.162 60 ft.
Lost traction

Thanks again to all, for the input.

Nice. Almost in the 13's now. Pretty impressive for that elevation and I'm sure the setup would have more in it at a lower elevation. I was sure a proper calibration for that MAF would help too. Keep working on it man! 13's a hair away.

Yeps, keep it up man.

I have to X2 this, a proper tune can make a big difference.

when you start making power you get to step up to big dog slicks.

It took a cool night, but thanks to N2O-OLDS, aleroboy, and the GrandAmGt.com network, 13's are here...as far as I know, this is the first Alero / GrandAm to do it at this elevation.

Test and Tune, September 26, '07 (Bandimere Speedway) (Elev. 5860 ft, temp. 60-65 deg. F.)

Air filter bypassed, Malibu wheels (front and rear), D.R's, Stock LS1 MAF, muffler removed, spare tire and floor mats removed, iced IC.

1) 13.946 @ 97.96, 2.037 60 ft.
2) 14.263 @ 97.40, 2.231 60 ft.
3) 14.054 @ 98.25, 2.160 60 ft.
4) 13.892 @ 98.01, 2.083 60 ft.

Still got traction problems, and the scans were ugly, but I'll take it.

Answering the question -- how much can a stock engine, tranny, and a little M62 take? We'll find out.

221 timeslips in 4 years..... WOOOOHOOOOOO !!!

[AaronGTR]

Awesome man! Congratulations.

[aleroboy]

how much boost is it pushing now?

[GT_turbo]

took 4 years to reach 13's with a supercharger?? I've had a turbo for 1 month and I'm pretty certain I'm hitting 13's at 10 psi.

reading is a virtue.

he never said 4 years with the supercharger, just how many slips have been accumulated in 4 years.

also, check his elevation..he has had more hurdles to overcome.

Its too bad your car runs like **** though

Why cause I had a few electrical problems that I got worked out already??? Don't be jealous man.

people have said it to me when I've been boasting about "potential" times, and I'll say it to you. Don't talk TOO much about it until you do it.

For the record I did 13's with less than 10psi.

Hey Alerob888..........
How did this kit personally work, Im going to do the same thing, just curious if it made a real difference?
Also, Even with the I/C you still have methanol injection? Does it help any?
Also if your using NOS do you need methanol injection? or could you benefit from both?

.................

This kit has been a real blast. So far I've always passed emissions tests, car has been a daily driver for the most part, too.

No, I have not had the methanol injection on for the last 2 sessions at the track. The one I had sprayed into the TB, upstream of the SC and IC. That particular system worked better with no intercooler in the setup.

The Alero ran between 17.05 and 17.4 stock at my home track, at 5,860 ft. elevation.
aleroboy did the original install of the complete Magnuson kit, with their air filter box, EGR setup, and a 2.5 in. pulley. I was getting around 5-6 lb. boost at that point, and I estimate it could have ran about a 15.7. E.T. up here.

I switched to a cold air intake and added the alcohol injection, then the Alero ran a best of 15.5 at 5860 ft. The rest of the car was still stock.

Next season aleroboy installed TOG headers and SLP / Magnaflow exhaust. Changed to a 2.2 in. pulley, Got about 7-8 lb. boost up here. The car went into the high 14's. A few other mods ( 2.5 in.TB, MSD box, MAF-translator), It went 14.5 at altitude, 14.0 at sea level on street tires and very poor traction.
That was before any real tuning capability was available to me. So, yeah it made a real difference.

[AaronGTR]

Wow. Solid in the 13.7's now, and a 13.6 too. Nice job man!

[TurboAlero]

That's on street tire's????

if that's on street tire damn it hooking up pretty nice

[SpyhunteR]

street tires 2.0 60fts... looks good.
