So as some of you know I have been trying to get GM to give up some more info on the 300+hp build. I got an email in reference to pistons as well as a little bit of a tease about future GM plans for our cars. Read below for more info.

Hi, Rod.
The pistons from the 300hp build were from Diamond pistons. We also work a lot with JE pistons. If you are interested in a new piston, I would suggest contacting JE or Diamond and telling them that you want a production-replacement forged aluminum piston that increases your compression ratio to something between 9.7 and 10.0:1.

We are working on an off-road box that will allow you increase your rev limit, run on 110 octane, and/or use a 50shot of nitrous. Please remember that there are a lot of hurdles and concerns for GM to release these types of calibrations. Because of all the issues that large companies are subject to, these types of things are typically done in the after-market.

cooooool! :

 

YES. I can't wait for our car's possibilites to open up even more.

 

Cool!,,, Keep Trying To Get More Out Of Gm!

 

I am working on it. Next I hope to find the part number they used to replace the 1\2 shafts as needed with the major increase in HP.

 

I thought they used the half shafts out of the Pontiac Grand Am/Prix? That's what they used on the Street Tuner Challenge car atleast.

 

The Drive Shaft Shop can make a performace half shaft for you as well. They are expensive. An even thousand for a set. And you won't have to replace your hubs or drive flanges like when using the Grand Am set up.

 

I hope they plan on including some beefier cam springs w/ that "off-road box", I thought 7k was around the limit for the stockers? That's pretty exciting news none the less.

 

I will contact them and see about getting a set. Thanks

 

I contacted Diamond Racing and they have the pistons that were used in Time Attack car 9.5:1 and some 10:1 like were used in the Lakester Bonneville car they are Diamond p/n 10101 and 10103 $90.15 each piston.

 

I'd like an 7850 rev limit with the addition of Ferrea Valve springs and better rocker arms!

 

INTENSE has piston assembly for the LSJ insale right now with 10:1 and 10.5:1 comp. ratios.

as far as the Valve components, JBP has them for sale now. you just gotta find a way to program you ECU to a higher Rev Limit. ( yah I know Easier said then done )

 

is it safe to run those ratios on our car?

 

Sweet!

 

i'd be interested in this so that i wouldn't have to get a stage kit for a 7k redline... since i'm going aftermarket for injectors and pulley's and a tune.

 

with the comp. raito going up with them would that limit the boost you could push. why not just do away with the comp. ratio and just get a bigger s/c?

 

cuz a bigger charger wont really do much for us, let alone the fitment issues along the way.

 

I got a hold of them and this was the response.

Rod
we have written programs for the axles and will be making them in about
2-3 weeks, if you need them sooner what we have been doing is haveing the
customer send in the axles and we re-use the factory inner c.v. and make it
chromoly out from there. the factory inner is a mild chromoly and is good
for about 350HP to do this is takes about 3 days and the cost is 600.00 (the
complete axle will be 800.00 for the pair 400HP) you are welcome to post
this info if you want.

As for pistons I talked to Todd at Intense and he recommended (for my plans) to go with the 10.0:1 which I have. Also I went with the JBP stage 2 head because of the titanium springs and retainers.
Also for Canadians I found a place in Ontario that sold me the cluch in my signature for $810. Can shipped.

 

^^^Nice! I think I'll be needing a set of those in the long term future for my car.

 

 

a company has had the electronics from that box for a while now and they're going alot further than what it came flashed with

 

and what company would that be?

 

Yes selfinfliction, please tell us. As you may know I am close to doing the 300+hp build and I need that kind of info so that I can tune this car to accept the cams\pistons I am using as well as raise the red line.

 

All good news!

 

update?
