I have heard the conventional wisdom that "you can't turbocharge a type 4 successfully." Is it just difficult, or can it really not be done well? I'm tossing around the crazy idea of turbo'ing a type 4 for PCA club racing, to put in the chassis in my avatar. My 6 in its current configuration is not competitive, so I can put a bunch of money in that, or do something different. I like a challenge, so why wouldn't the following work?
- 1.8 or 2.0 type 4 as a base. I would keep displacement stock or close to it. - EFI for induction - Properly sized intercooler and huge oil cooler - A good aftermarket cooling fan - Would be dry sumped - I would work with a knowledgeable builder or shop to build the engine. I am not so familiar with type 4 race modifications, but presumably this would include reinforcing the bottom end, using Carrillo, Pauter, etc. rods - Obviously the heads would need to be reworked for flow and possibly reliability If I do the above, could a type 4 be built to withstand 15 psi of boost and make 350 hp reliably?

Burning alcohol would keep head temps down. Add power too. Is it legal?

Burning alcohol would keep head temps down. Add power too. Is it legal? I've wanted to do this for a while on my 911 motor, and would make sense to me for a T4 turbo as well. Unfortunately, not legal at the moment for PCA Club Racing. I looked just yesterday to make this suggestion again, but it seems the period for submitting suggestions for 2017 rules closed in August. I would suggest E85 actually, which gives a more visible flame than straight alky when on fire. I understand that the invisibility of alcohol fires is why some has reservations about its use. Maybe next year ... |
