Camaro LT5

[Stielow]

For what it is worth we chassis dyno-ed my car on Friday. 812 HP to the tires. On winter blend 93 octane fuel.

I have put 200 miles on the car so far and did get a chance to stand on it yesterday. First off it is sketchy fast on 32 degree tires. With less torque than the 427 engines it is a bit easier to pedal to keep straight.

The high boost 6.2 liter sounds different from the lower boost 7.0 liter. It revs quickly and hits hard. My un-scientific test of a sprint to 150 mph this car is on pair with my past projects. (Of course closed course it a professional driver).

On the prototype mufflers that we had made. They are LOUD. Like squirrel dropping out of tree loud. Like setting of my neighbors car alarms LOUD. You know LOUD. On a positive note it has a very deep note at idle.

I will get Hooker to redesign the mufflers and add resonators. We are doing a little R&D for Hooker Black heart.

Been there tried that. We added a 1 quart over flow tank in the trunk. It is the way highest point in the system. Then we vent off the top of that to the Too Much canister.

I’m sick and tired of the fuel puking out. It seems to work great. I fully filled my tank with very cold fuel and then parked it in my heated garage. No fuel smell and no signs of over flow.

Done. Fixed it. I hope. We will find out this summer.

Ok I have 200 miles on Apex now. Getting some bugs worked out.

Clutch is working smoother. Katech has the cal closer. Car hits the tires fairly hard.

Low effort burn out. On a 60 degree MI day it seemed like the thing to do.

So far the hi rpm reserve is very good. I have not tracked it yet but form the little bit I have drove it I like it. (I only have 200 miles on the car).

DYAD 7.25/10 rating. Negative rattles at idle when it has some miles on it. It too can chatter sometimes. Need a custom throw out bearing. Great high rpm reserve. Work awesome on the track. No issues.

Tilton 8/10 rating Does not rattle at idle. Does not need a special throw out bearing. Had a small chatter at a very soft launch. I have not tracked it yet.

Good info, thanks. The Tilton sounds very promising, and at a reasonable price too. Look forward to more info after you get more miles on it. You went with the organic discs and not the cerametallic discs, correct?

Mark, It never get's old. The perfect stress reliever...

The issue is the Ricks tanks and most aftermarket tanks do not have room for expansion.

This one of the only issues we had with Charlies new Riv.

The 2 Much canisters do a great job with fuel vapors but no pure fuel.

I may add an expansion tank to the project before the 2 Much canister to keep raw fuel out of it.

Thanks for the comment I almost forgot about that.

I’m going to humbly disagree with Mark. The older version of the Rick’s tank uses an internal manifold/tube which may cause the tank to pressurize and push liquid fuel out of the vent port when full . The internal vent tube seems to act like a straw that can submerge the vent port in fuel when the tank is full. Newer Rick’s tanks appear to have abandoned the internal manifold and switched to a two port design. A port on the filler neck and one strategically placed on the tank running to a T and then to the VSB or VSR has worked well for many II MUCH customers even in road race applications.
The Riveria also had the internal manifold design, and overflowed as I predicted in conversation with Sled Alley after I saw a picture of the tank on the build thread.
If you scroll to @motobrewmaster ‘s post in this thread you can see one of the older Rick’s tanks modified as described — he plugged the original port location on the front of the tank and added three new ports. Three is probably overkill but certainly can’t hurt.

That said, Mark took a sledgehammer to the problem and is happy with how things are working for him. I’m happy to continue this discussion with anybody that is interested privately.

Next stop Scottsdale AZ for the Barrett Jackson Cup car show.

Good thing Charlie hates white or he'd probably keep it in AZ.

Hmmm... I need to look this event up, see if I can make it over to the East Valley for it.

Agree. On my older ricks tank with the tube I had overflowing issues and my overflow would hose fuel. With my new ricks tank and 10 or 11 gallons of gas I have zero issues
