[COTW 10/3/11]: My Texas Speed E85 429ci & 4L80E swap
 
1 Attachment(s)
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.

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

Do you have a breakdown on the weight reduction?

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!

JETG 09-07-2011 06:29 AM

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.

thesnoopster 09-07-2011 05:36 PM

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

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

Supercharged SS 09-07-2011 05:46 PM

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

speedster 09-07-2011 06:16 PM

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:

Ucantctchme 09-07-2011 06:18 PM

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.

kaler 09-08-2011 01:56 AM

: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.

andredmg 09-08-2011 07:11 AM

Im already growing impatient lol, been checkin in everyday ha ha. I think you're gonna make a lot more than 575 to the wheels homeboy trust me.;)

Did some work today, finished removing the old engine, few shots of misc and shit laying around my garage. I work full time (army) and do all my own work at my own pace, so appreciate that this isn't a big shop build with a lift and air tools. Craftsman baby. Here are a few shots from today, including the offending cylinder/piston in the old motor.

The majority of the scarring is literally right on top of the first ring. What could conveniently fit there. A burnt off electrode perhaps? My conjecture is the cyl got hot, burned up the plug, the molten electrode fell, cooled, ended up flopping around until it got stuck between the piston and cyl wall, right above the ring. I believe it got stuck there, and went for a ride all around trapped between the cyl and cyl wall. It's the only thing I can honestly think of that could have caused the cyl markings the way they are. Pics look ugly, but they aren't deep at all. Rod journals look brand new. Rod bearings look brand new. Rods look brand new. 7/8 of the pistons look brand new. Thankfully this means my short block is still worth some coin, which will contribute handily towards the new setup. Stock pistons are coated. Who knew.


Rear suspension and DSS/Hendrix axles, just hanging out. BMR Drag bar!

On the to-do list is to handwash the underside of the car, and suspension parts with some simple green and a cloth. Filthy under there, and what better time to make it shiny and new looking again then when its in the air and empty of driveline

5thGenCamaroKid 09-09-2011 01:51 AM

:coolpics: Wish I had the knowledge to execute this in my free time.

DietCoke 09-09-2011 02:25 AM

When you break it down barney style, it ultimately is

Step 1: Remove all bolts and connectors

Step 2: Replace all bolts and connectors.

All the rest is just icing on the cake. I need a receiver for my garage speakers!

thesnoopster 09-09-2011 06:41 AM

Nice DIY work :clap: :thumbsup:.... someday I will probably do the same.... thats someday LOL

Padre 09-09-2011 07:32 AM

I didn't realize you had blown the motor. :( The nitrous a culprit?

I went down a similar path in 2005 on my LS1 GTO. Melted some pistons, pulled the motor, and threw in an iron 408 I built in my own garage at the church. :)

Enjoyed every minute of it. Hope you do the same. And keep the pictures coming! :)

DietCoke 09-09-2011 09:20 AM

Indirectly, yeah probably. Spark plug melted, and the electrode looks to have scratched up the cyl (lost compression on #6 as a result). It isn't "blown", but it was hurt. Real easy to clean up though.

Oh sure, a little honing, all that. But better yet, a good excuse to drop in a 429. :paddle: :D

JETG 09-09-2011 10:40 AM

Might do this myself. I use to work on all my own cars, might have to start again. Just get some stuff done at shops. But I would want a compresser and air tools for sure. I would guess you just have it all up on stands ??

DietCoke 09-12-2011 05:43 AM

No major updates, sold the remainder of the factory shortblock, got the heads stripped bare ready to be sent off for a special 280cc cnc port. Got a guy coming to buy the trans/clutch tomorrow and it's then time to get the 4L80 ordered. Parts recycling ftw.
