you also need an oil pump to return the oil back to the engine. i cant wait to see how your going to do this! i would love to put 2 turbos on my 73 riv!
Your Riv probably has more than enough room to package them properly under the hood with a real intercooler. What kind of engine mods have/will you be doing in preperation for that?
Thanks CTX for the input, replies from turbo guys are much needed here. I am still gonna keep an eye on the STS rear ideas. Their website does a good job of explaining the physics, but obviously they are gonna cloud the negatives if there are any because they need to sell their product. I will definitely be asking a lot of questions more than ever.
How is it going? Curious myself. This is such a cool endeavor. I'm living vicariously through you. :TU:
where would you put the turbos in the back so they would be out of the way? i have an idea for you, run your AC through your intercooler to increase efficiency :laugh: this makes a new idea in my head, maybe next time.
Rear mount Gm High Tech Performance magazine (or whatever it's called exactly) did a feature awhlie back on a rear mount turbo set-up for f-bodies with LT-1 and LS-1 motors. According to the article there was (surprisingly to me) almost no turbo lag and like Jim said the plumbing is the intercooler. What about 2 GN turbos since a 462 is exactly twice a 231 and 350 hp out of a GN is easy? Twin turboing my motor that way has always been one of my fantasies :Brow: . Good luck!!! :beer
So you guys are running efi on your 455's? Home fabricated or is there actually a stock 455 efi source?
The aftermount turbo is by a company called squires turbo systems. STS makes kits for most later model vehicles, single and dual in the 5K to 14K range. The benefits are numerous, including cooler underhood temps, less lag than a conventional system, faster spool (you're using a cooler(more dense) exhaust charge, and in the case of a single turbo system, a more powerful exhaust charge due to the fact you are using the entire engines exhaust) a much simpler install, (no manifold to fab), no intercooler to install, a cleaner engine bay, and much cooler running turbos- which in turn means more efficiency, and a longer life for your turbos. The downsides are minimal. Cost is a little higher than doing a conventional turbo on a late model vehicle that has a kit available, and you have a very distinct (euro sounding) exhaust note, oiling is an issue, but they have pumps available, and 1 pump will feed two turbos with super cool oil no problem. You don't need mufflers for this system, single or dual... I have a design in work, but I need to make a custom efi manifold first... the rest will be pretty simple and centered around a fast efi system. I've done camaros, hemis, and one Impala (we hybrided a kit)...Awesome stuff!!
