Your Cadillac is awesome by the way! I've got a customers 57 De ville Coupe here that we'll have on the table soon and I've been sending your photos his way for ideas! And the bed liner is nice for cars like this 4 door. I really don't want to put too much work into it since it'll never be worth anything. The ongoing joke around here is that when we want to sell it we'll pull the body off and get more money for the frame by itself.

It looks to me that the Cadillac has a bit more room under the hood compared to a TriFive. I don't have that all scanned into the computer so I can't quote exact number unfortunately.

I've never experienced any noticeable lag VS tire spin with the STS cars I've been in or built so I can't comment there but I would guess that the turbos were not sized right or the exhaust tubing was too big. I drop the exhaust tubing one size to help raise the velocity of the gas to the turbine as well. It also saving money, weight and time on the installation. For the remote turbo systems they offer sealed turbos now so no more oiling pumps or lines so we don't even have to worry about that weight or leaks any longer. 50lbs that far forward and that high makes a huge difference on the roll center and CG of the car. Just imagine that much weigh with that much leverage over your suspensions roll center as you turn into a corner causing pushing on the front suspension.

The return tubing on my PT-57 truck was all aluminum and was less than 15 lbs total when the truck was done after I removed the inter coolers. I removed the inter coolers from that system because all the aluminum tubing made them redundant. I have this picture but I can't find the written weight. You can see its on a scale and its ticking my off that I can't find that number. All this weighted coming out from the front of the car but I want to say it was 20-25 lbs. And that's off the extreme end of the noise from the truck.



When I had the truck on the dyno the dyno registered 72F as native air temp and my IAT sensor at 6 psi was 75F. We had leaks I didn't have time to hunt down and a really really foul spark map that we couldn't correct I found out later what that was. We used hand held Pyrometers all over the system showed only 5F of heat drop across the IC when it was on the dyno so the only air was from the fan right on the IC not even air flow across the chassis that would cool it even further.

If I was running a built motor or hard core racing I would probably run front mount turbos as well.

Thanks! If you've built/driven other rear mount turbo cars and like them it's all good, just a matter of preference.

I think the Cadillac has a bit more room than the Chevy though the car I was speaking of was a 57 Chevy with LS3 and 2 small turbos. Has stock 5th gen Camaro manifolds in original orientation with up pipes sweeping up and forward into the turbos.

Looking forward to your chassis pics

NICE!! Got any photos of that one?



Minion #1 has some awesome body working skills. This was a surprise to me. Body and paint guys have been a thorn in my side ever since I got into the Hot Rod business and to have a good one working for me will make my life much easier in the long run.

Originally I was telling him to go easy since its only a 4 door and tons of body work won't be worth anything in the long run but I started thinking about it and decided what the heck. Go nuts. Make it as nice as you want so we can see what he can really do and so far it amazing!!!! I just wish I could have him for more than 10 hours a week. I mean, LOOK AT THOSE DOOR JAMS!!! Its going to be gorgeous when he's done.

This is the first round of primer on the quarters. I didn't want him blowing time or mud on the stuff under the fin but we decided later that we didn't need a place for water to just sit and fill up.



This is a TFC4-S4, TriFive C4 Stage 4 Rolling Chassis we're working on along with many other project in the shop.



All by hand as well. He has only touched a single power tool the whole time and this is after the second round of primer.

Following this. We have a '57 4-door 210 sitting in our garage that we are going to get started on soon. It's funny because I also have a relationship with the guys over at STS turbo.

Looking good!
