[COTW 10/3/11]: My Texas Speed E85 429ci & 4L80E swap
 

This thread will be updated as I have new information or parts pertaining to the build to announce or show, as well as being fully documented in pictures.

The goal is to run a 10.XX n/a, and to have the fastest n/a 5th gen. The car is currently down to just under 3600 pounds (yes, I've done a LOT of reduction) but still retains a full interior including backseats. I expect to add 50 or so back with a bar, but it is substantially lighter then your avg 5th gen.

Component List from Texas Speed & Performance, expected build time: 3 weeks.

Nothing too exotic or special in the bottom end, just basic forged components, but note the +3cc pistons. Going to couple these with a 64cc head for roughly 13.5:1 static compression, should be a blast on E85. :headbang:

The extra compression is obviously a free horsepower/torque bump, but should really make the car sound plain nasty. Once I get the super secret squirrel LS7 heads back from TSP I'll post some pics and flow numbers, and then it's time to spec out a camshaft. (Something monstrous, 25x/26x .650+ lift)

For a transmission the TR6060 is out. As much as I enjoyed having the manual, it really is counterproductive to putting down a number with any sort of consistancy at the race track, and was becoming more of a bear to drive the faster my car was getting. To remedy that, am swapping in a Jake's Performance 4L80e transmission, with Andy @ ADM's trick crossmember addition to mount it. Sourcing a billet stall from Circle D (4200-4600 planned) and a large trans cooler to finish off the transmission package.

DSS will be making the stock rear --> 4L80 driveshaft. I believe I can keep a stock rear alive at this power level with an auto car, especially with the weight reduction that is in place. I have DSS/Hendrix Level 5 axles, and may eventually do the Janetty Caps/Billet Support cover for the diff, but for now I'm not too worried about it breaking.

Lastly, and most importantly, the intake setup. While a fast 102 seems like the obvious choice, I'm anxious to get my hands on a Holley pro-flo 102mm high rise for this motor. It should make significant power over a fast on something with this many cubic inches, and will be the last part I buy, as it's still extremely hard to get your hands on one of these. Figuring on 65 lb/hr injectors, but will upsize if the motor deems it necessary

Expecting at least 580 rwhp N/A :confused0068:out of the 429 through the auto, any more then that is just icing on the cake. Who needs a blower :laugh:

Pictures to come as parts start rolling in :D:chevy: I hope to have this project finished by the end of winter/opening of race season next year.

I'll be watching!:popcorn::popcorn::popcorn::chevy::w00t:

:popcorn::popcorn:

sounds like you have quite a good plan there :headbang:

:clap::popcorn:

Do you have a breakdown on the weight reduction?

Padre

I'll work on that on the side, just to make a detailed list, but I don't have an itemized weight, no.

Nice looking build!

Sweet build, been tossing up ideas on how far and how soon I want to put it all together. I am thinking motor and nice dose of nitrous, something along the lines of what your doing. Good luck on the build, and will be suscribed for sure.

Awesome build. Subscribed.

That my friend is a nice build you have in the works! :thumbup:

I will be keeping my out on the progress :thumbsup:

Good luck brother! And I need a blower!!!;)

Great build you have here. Can't wait to hear this one run.

13.5 CR will give spectacular throttle response and sound so sweet... :thumbsup:

If your planning on spraying on this engine make sure the intake doesn't have a dispersion issues. On some of these intakes some cylinders will get more/less nitrous depending on flow characteristics. Even worse would be if the fuel fell out of the stream or condensed in the intake. Just sayin cuz it's new to the market.

:drool: Very nice build. Mike the owner of GDP performance has a built 427 in his vette. That he runs on E85 13.5 CR, ported fast 102, 80lb injectors :confused0068: It is the nastiest sounding modern car I have ever seen on the streets. It is an impressive car to say the least 650 RWHP.
