Finally got the .81 AR turbine housing switched back to the more correctly sized .96 AR, ditched those powder blue 11mm Moroso wires for a set of red MSD 8.8 race wires, also replaced the distributor cap and rotor and the plugs. When I first got the car back from Dan's shop (trailered it home because of heat) I quickly found that it had a missfire under a load or at high rpms. Rather than trailer or drive the car back to his shop, Dan came over to my house earlier this evening and we tested all the wires and put in another set of plugs. We found the #6 plug had a cracked insulator, but still went ahead and replaced the rest of the plugs just to be sure.

It fired up much easier and revved clean and crisp. My concerns about the larger turbine housing making the car too laggy were quickly put to rest on the test drive, because it spooled just as quick as the .81 AR housing did, but felt even stronger. Even in the 95 degree heat and high humidty the car is insanely powerful and instantly put my new tires up in smoke and pegged the tach. Shifting to higher gears doesn't do anything except make more smoke. Did a quick trans brake test and boost got to 8 psi before I even reached the 3400 rpm 2 step setting...letting go of that button took another few hundred miles off the tires :D

In a few weeks we are supposed to take it over to Craven Performance and see what it will do with race gas and more boost. For that test we will also be removing the tiny air filter. Here's a picture.

Nice!!! Do you have any more pics of your turbo setup and pipe routing??? I want to do something like that in my 4v 95.
This thread has several pictures of the original build.

This link has lots of pictures and a full list of mods.

Since this was fist built I've made numerous changes/upgrades to the hotside pipes and the exhaust system, but the general layout remains the same.

That is a pretty sweet layout. I like the idea of putting the turbo where the airbox is because of all the space in the right front bumper. I see where you had trouble with the A/C lines. My a/c hasn't worked for years so I might have to do the same.

The 347 should breath alot easier through your .96ar housing, you've got plenty of displacement to spool it reasonably quick. That looks like an incredible amount of work and dedication. Im amazed you can fit all that under a stock hood.

Thanks for the help and Keep up the good Work :thumbsup:

Planning to race it in the SC/XR7 Shootout in Dayton, OH next month and see if I can get it into the 9s.

Pulled 701 rwhp last week on a Mustang dyno, while getting the race tune dialed in for the Shootout.

Yeah it was skating a lot in first and second gear and I had my hands full just keeping it pointed down the track. No matter what I did with tire pressure or two step rev limiter settings, or even removing the passenger seat and spare tire, it just got worse on every pass. I think I'm reaching the limits of the bone stock suspension to hold the power. If I could just keep the rear end planted, it would have done a lot better.

If I had not blow off an intercooler tube on the first two passes, I think it would have gotten into the 9s because at that point of the day there was still plenty of rubber on the track from a race event that was held the previous day. This video was on my 3rd pass and ended up being the best of day. Mike Siska was having similar problems with traction.

While most people were down about .50 seconds from last year because it was warmer and the air wasn't as good, I had no shortage of power, just couldn't use it. My class ended up getting cancelled because the other cars broke or had problems with the tune, so we ended up bracket racing the 4 fastest cars. I was more interested in getting a 9 second time slip than winning the race and stayed on the trans brake a little to long racing against a car with an 11.48 dial in to my 10.00, and ended up spinning the tires for all of 1st and 2nd gear for a 10.56 @ 128 :(

PS: Getting slowed down after clearing the traps was not fun. I need to put a vacuum canister on, because the brake pedal was rock hard for the first half of the shutdown with no power assist until it built up some vacuum :eek:

Bruce,

My daughter is very close to having a baby and I promised her I wouldn't leave town again until after she is born. Last time I raced in NMRA true street class, I had to get off the gas at the 1/8 mile for the first two passes, then on the last pass we got a 10% faster than you are legal to run, free pass. Since I was legal to 11.50, that allowed me to run as quick as 10.00 one time without getting DQed. I really enjoyed the format and watching all the other cars race and would like to go again.

We are planning to attend the KY HP assoc fall Shootout in Clay City, KY on October 23rd. I'll most likely be bringing this car and take another shot at getting into the 9s, because it's a private rental and if I race in the test & tune class they won't kick me off the track for not having a cage. They also have a much longer shut down area, which is nice.

Yea, the no roll bar or cage does limit you. I was asked to park mine a few years ago before I put one in it. I am now well below the 10 point roll bar cut off, so only run it at non NHRA events a few times a year. With a little more traction, you would be into the 9s I am sure.
