Lil IHRA classification help please!! Newbie Alert!

[KennyAnderson]

OK!! Picked car up on sat am, mounted wheels and tires and went racin sat sun. Not bad although a lil slower than I had hoped. It was AFRICA HOT THO!! Ran 14.30's and high 9.teens/20's in the eigth. Fairly consistent and easy to hit the tree in. Looks like D/PS it is although I will need to get just about 100lbs out of the car and speed it up considerably with an 8.50 index. First thing on the slate is a converter. The stock one is TIGHT! Can barely footbrake it to 1500 before it pushes through the brakes. Looking at a Yank 3800-4000 stall. Any pointers? And guys with experience how much did you pick up with a good converter. Most say 1/2 sec should be easy with a good one. Headers and gears next up.

Shoot me a PM and I will give you my opinion

We put a Yank SS4000 converter in along with a 3.90 gear (stock is 3.15) and drove it to the track on a drag radial and picked up one full second. 60' times were in the 1.60s. A half second from just the converter (assuming it will hook) sounds about right. If you want to order new call Yank and get a recommendation ... they know their stuff. However, if you look around on the Camaro and Corvette forums you can usually pick up a nice used one for about half price.

PM sent. Thanks!

Thanks Scott. Did it pick up a sec in the 1/4? If so how much 1/8th? Either way IMPRESSIVE. Got a line on some headers, gears next. I'm hoping between these three main things (converter, gear, and headers) PLUS getting about 100 lbs out of the car I can run the index or better. Need 7 tenths in the 1/8th (8.50 index).

It was a full second in the 1/4 ... I don't recall what we picked up in the 1/8. I'd have to refer back to our log book. I do know our car runs further under in the 1/8 than it does in the 1/4. ??? Don't forget to get a tune. If you can swing it, and have someone local who is reputable and knows what they are doing, a dyno tune is always worth the extra money. Some folks are going to tell you a mail order is fine but PM for my personal opinion as well as some bad experiences that I've had.

Luckily I have a longtime bud down here about 30 min away who is a guru and has a chassis dyno. One thing I am going to look at is a shift kit or manual valve body. This weekends shakedown showed me a few things. The old owner said he shifts it himself @ 5k. I tried shifting it as well as leaving it in drive. When I shifted it a 5k it didn't really shift till about 5500-5600. When I left it in D it shifted itself right at 5600. I felt like it was nosing over just a tad both ways. The et was faster by .04-.05 shifting it. I really feel like short shifting it a lil will help a bunch.

That's good that you know a reputable tuner. That can make all the difference in getting a car to run the index as well as having a reliable, consistent Stocker.

Speaking of consistent ... I've never shifted any computer-controlled car that I've raced. Turn the traction control off, put it in drive, and go. My thinking is that I'll never be quicker than any computer and definitely I won't be more consistent. Even if I picked up a hundreth or two I want the consistency. When we work hard to regulate the water temperature and ice the intake if traction stays our car is deadly consistent on the ETs by not shifting it.

Hey. Kenny

Will be replacing my YankSS3800, installing a new Yank PT 4200 getting the trans rebuilt in next couple months.
When do you need the converter?
The hold up is our 94 Caprice SSuperwagon is at Maaco getting body work done.
Soon getting 3.08's installed and prepped for Towing.

However do have very good suggestion to save money on experimentation.
Buy the YankPT 4400 or 4200 Stall converter right away.
Add Blueprinted cam matching springs, headers, gears, tune and you should be making one second under ET's.

I agree, I was just experimenting with what the previous owner told me. Going up to South Carolina tomorrow and I'll have plenty of chances to make hits Thurs thru Sun. One thing I learned and the ex-owner told me afterwards, it runs best at 160 water temp. I experimented at 170-180 and it did slow a tad. It will be tough keeping it at 160 tho if we get hot lapped, especially w/o an ele water pump. I expected a fuel injected car to run better when its warmer.
