Just to let you know the Mongoose Penske car is no more . It became one of the Fast and Furious Cars for the movie. It's now silver !!! It was and my new car is now painted the current Sunoco Blue which came about in the late 60's about 68-69. Color change came from the Pew family which at that time controlled Sunoco. As far as my sources at Sun know there have only been two Sunoco Blues in the companies history. ----------Ken

Finally had a couple hours to see if the Acura Integra Type R seats I have will fit the car:
We will have to make some new seat-back pivots, as well as mounts, but they don't weigh any more than the Mongoose seats, and they hold you in place without looking too obnoxious.
Just as Honda, I plan to use suede and knit when they are recovered in the correct colors.
My new quick-steer rack also accepted the shorter 1984 tie-rods, so the steering may not require too much fabrication when I install the narrower front suspension pieces. The new Wilwood front brakes are due here this week, so if we can get enough shop work out of the way, we'll slap it all together in the first few days of July.

Those seats will help you when you really want to step on it. I'm using these seats with 4-point harness.
Of course I removed the head rests.

Jay,
If I could find a pair, I'd probably buy them.
My Wilwood brake set-up arrived today. This will make my work week a long one.....I put their boxes up on a shelf so I'm not so tempted to look at them!

Any pics of them in the car yet?? curious how they will look. Without the headrest, they would remind me of a more supportive version of a cobra seat....

I have couple of shots of them when I test fitted them. But I'm on my way to Goodwood Festival of Speed and will be touring Europe for the next two weeks, so I don't have access to the pics. I'll post some new ones once I get back home. Size-wise they are perfect for my Grand Sport and feel a lot more supportive than the stock C2 seats. Sparco stopped making those seats last year, so they are pretty hard to come by...

First time with the Grand Sport at Hallett
Here is a video of my first time on a road course in the Grand Sport. The car did pretty well for the first time. Despite running a 3.08 gear, 330 horse iron motor, rear brakes locking way early and street tires.
We were able to run a few sessions before the 4 speed let go. I have a Dana 44 on its way with a 3.45 gear, that I am hoping to get in before the next time we go. Plus a brake bias adjustment valve to delay rear brake lock up a little.
I just couldn't catch the black Z06, but it was fun trying!

Thanks Larry, it is much more technical than I anticipated but great fun.
The car seems like it handles very well given our limited knowledge of road racing. Along with the 3.45 gear that is going in we bought a low mile ctsv ls6 and t56 for the car. Can't wait to get it in the car, probably be a winter project.

When I got serious, I replaced the rear gears with a 3.73 ratio, about the same percent change as you will see in going from 3.08 to 3.45. What a difference! That change really woke up #80.
I predict you'll notice a huge change also when you get that new D44 installed.

You sure are welcome Jay, now we are waiting for you to post a ride like that in your GS.
Jim, I am looking forward to running it with the 3.45, it is going to really wake the car up. I feel like we will end up going with a 3.70. We have a ls6 and a t56 out of a low mile ctsv coming and a 3.70 will be much more compatable with the .50 6 th gear.

The video is awesome. Thanks for taking the time to post it. With the new engine you are putting in it, how much horsepower will it have over your current engine?
Thanks again, I have watched it several times and dreamed.

The road race forum guys all talk about the LS1 and LS6 as being very reliable without a lot of modification. The ctsv was the only combo we found to use the LS6 with the T56 mated to the engine.

The LS6 was used in the 2001-2004 Z06 and was rated at 405 HP. We think with a few little tweaks it should go 425+ pretty easy. So it will be 100 HP more than the iron 350 we currently have, but the real key is the LS is suppose to be 125 lbs. lighter than a iron 350.

Smaller size, lighter weight, more reliable, better fuel efficiency, easy to get tons of power... What's not to like.
#240
Jay I have been putting of learning the LS engine and it's operating systems. You hit the nail on the head tons of power, reliability and very light weight. Can't wait!
