Source Automotive Twins Installed

[paulb]

I stopped to see Rip last week, and we started talking about turbos. The discussion led to either a bigger single or twins. Rip offered to let me drive his truck, to see how I liked his twins. The bottom line was I now have a set of twins installed! Oo.



The turbo's are S400 on bottom, and HTB2 62/14 on top. I've only put about 400 miles on the truck since the install, but the spoolup seems to be as good as the Dodgezilla I had on it a year ago. EGT's are down over 200 degrees (comparing it to the Cool Twist) when on 5x5 on the comp. EGT's at cruise are also down. I also can't believe how quiet they are!



Needless to say I am very happy! The kit is well made, and fits very well. Though it is hard to tell, the pipes (except the hot pipe), are powder coated, and IMO look very sharp!



Here are some pics that I took with my camera phone (not very good quality...



First all torn down, ready for the install...

They sure are Purdy! Sounds like Rip and Scott Radke have found a liking to that HTT 62/64 S400 combo. Glad to hear you like it!

The S400 is a great bottom charger. All the flow of a 3B with better spool. Pick your flavor for the top but anything with a big wastegate that will spool quick will put a smile on your face.

Congrats, looks like a nice set-up! Sounds like I might need to consider twins again!

I was just doing some reading and it got me wondering, is the S400 the same thing as a B2?

 

[BTighe]

im pretty sure it is.

Very similar.

Paul;

where can I get information and costs on this set-up?

Is it available for first gens and second gens as well?

The set-up looks great!

A couple of reasons. One the Cool Twist is a lot bigger then the 62/14 that I have on. The big reason though was that the exhaust housing on the Cool Twist is longer then on the HTT turbo's. By using one of the HTT turbo's I can change from any of the sizes, without changing hot pipes or anything else. At this point I'm not sure why I would want to though. Oo.

Harry,



Contact Rip at Source Automotive. The toll free number is: 866 211-1533. I know he has them for both 12v and 24v second gens, but I'm not sure about first gens. There were two 12v second gens having twins put on, while I was there.

Looks great Paul!!



When I was at the shop several weeks ago, Rip was mocking up a 1st gen. I do not know if they are done or not.



I know of 2 more guys that are gonna be running these in the very near future... .

Thanks for the hook-up, will be contacting Rip for info and prices.

Quick question: Why powder coat the cold pipes? I mean, you want that pipe to dump as much heat as possible between stages, and powder coating insulates.



Me, I'd personally love to see some kind of cooling between stages, be it water injection, intercooling, or what have you.

How about circular cooling fins like a big air compressor uses to cool the compressed air before it reaches the tank.

 

[SRadke]

Dumping heat would be great but honestly, how much does a thin layer of powder coating insulate compared to bare steel? I suppose you could make it up out of aluminum and polish it, that's be cool. Alternatively you'd have to come up with some kind of air/water intercooler.

The quick and easy answer is that they really look good! They are available either way.



Without testing, I am really not sure how much of a benefit it would be. I made a 12. 42 @112 pass yesterday, and I know the cold pipe was cool to the touch. Currently the max psi in the cold pipe is probably only about 30 psi. After I o-ring the head it will be about 50psi. It might be more of an issue then. My total boost is currently 58psi. Did I mention that the powder coated cold pipe REALLY looks cool? :-laf



I know this has been discussed before and I don't what to rehash it, but if someone were going to add another intercooler, I think it would be better to do it after the air has been completely heated. Also I would not want to inject water (or other liquid), before a turbo. Compressor blade erosion would be most likely the result. But... Try it and let me know how it works!
