I'll say. It looks like my back yard (not literal but close). Where is that?

Took mine out today for it's first real drive with the new 3.90 gears. I'm now running 245/45's and It is fine for the highway, but I wouldn't want to run a smaller tire size than that. It accellerates faster than ever. I can pass cars on these single lane highways much easier. That's not a butt dyno, but real world experience. It goes from 70 - 120 MPH faster than you can say, "What kind of car was that?" That is one serious rush.

We had a great week, i road about 650 miles. There was 25 of us from the snowmobile club, i usually ride with the faster members. The trails were really smooth and there was plenty of snow.

We rode out of Jackman Maine. The picture is from Colburn Mtn. Last year we rode out of Rangley about 75 miles to the south. The year before we did a loop on the The Gaspe Peninsula (Gaspesie), in Canada.

Some more pics. The Grand falls.

Yeah, it looks ccccold!
I just wanted to add that my limited slip set-up does indeed want to jump the tire on tight turns. Actually, a simple 90 degree turn from a stop sign on a narrow street. I felt the rear grabbing. Anyway, that's what I wanted, so I'm happy about that. My friends like it too, but they have Detroit lockers, or spools, or redneck welded rears!

OK, back to racing. I was having some trouble with hesitation, stuttering and surging last year. The problem was traced to bad plug wires. The noseing over feeling past 5000 rpm is now gone and the car is pulling hard and smooth.

I have been knocking off low 14's at 101 to 103 prettily easily but could not really hook up on the Nitto dr's, especially on the colder nights.

Last friday we had a nice warm day and i got the Micky Thompson ET's  back on. I had a real good night. I was actually spinning the MT's, i don't think the track was prepared to well. I ran 13.73, 13.78, 13.89, 14.09 and one crap run.



The 14.09 with .003 light, about 18lbs.

Wow! that looks very good to me.
So what do you think of the gears on the track? Improvement, the same, worse, etc...?

StarquestRescue -- Do you still have the 4.22 gears available to sell?

Old thread, but i never really wrapped it up.
The short answer is my car was no quicker at the track with either the 3.90 or the 4.22.

It did pick up trap mph a little. I will say it was easier to get a good et with the slow spooling turbo i had then. Now that i have a different turbo and more power i have no problem getting out of the lights or pulling the stock 3.54 to the top of my power band.

The lsd re stack worked great at the track. I could really tell the difference during the burn out. It did chatter a little on the street.

I sold the 3.90 to a guy with a auto car and he was quite happy with it. I started another 3.90 build but never finished it. Maybe i will have it done in the spring.

The 3.90 worked best with my mt et street slicks, 26" tire. At the time i had stock size street tires and the extra rpm got old. Balance shafts would have made a big difference. If i would have had 255/50's for the street it would have been better. It was also real easy to spin and over rev on the street if i got on it in first gear.

For some trans swaps like the say the t-56, gears would be mandatory. Or say a 4g car with a higher power band and less torque would probably like the gears.

Yeah, with the 3.90's, at first I felt like even a stock engine would benefit, but now after driving more, I think they really need an engine built for a little higher power band. I would say forged pistons and shaved rods are a must, and enough flow to not give up at 4500 like the stock cam and smaller turbo combinations do.

I don't have track results, but mine with the 3.90's is a great set-up. I can drive on the highway no problem with a higher average RPM because the engine is built for it.

Yes, we all seem to agree that even a stock automatic set up would benefit from the 3.90's. I have an auto car that I hope to put my other set of 3.90's in eventually.

The beefier stack sure helped on mine too, but does act like a lock up in parking lot turns.

Oh, and I agree about the tire size too. 255/50's are a good size for a manual 3.90 car. That puts the overall ratio a lot nicer for street driving, especially with an engine with a relatively stock power band.
