Phil,
i was not implying that you were stupid, the moderators get picky about that.
its just that off the shelf aftermarket throttle body injection systems cost a lot of money for mediocur performance.
tel us about your car, is it a corvair or what?
Hi John.
Don't worry, I did not feel insulted. Throwing $1600 + at a throttle body that would not improve the current 4 carb system would be indeed stupid. I had no way to know, having no previous computer management engine experience.
My build is my second seven. The first one was launched in 2009. (see Philippe's diesel seven in the finished build section) First as a diesel VW TD powered rig and then later as with a conventional 1.9L VW jetta gas engine.
My current build will be powered by a 1965 6 cyl flat 2.7 L Corvair rear engine with IRS which I am rebuilding . I have changed the seven chassis design to accommodate this rear engine. The 1965 Corvair engine that I have produces 140HP @ 4500 rpms stock with four carbs. I have bought a mild race cam and a header., as well as a small supercharger which I plan to run at a moderate 6 psi. My hope is to get 180 hp out of this mill.
As the Corvair is air cooled, heat is a challenge. I have designed the chassis to provide large air flow intakes in front of the rear wheel wells . The engine will be equipped with a larger oil radiator with electric fan. I have also built a 6 gal water tank which will provide direct water injection (mixed with intake air) at the blower level (this system has not been finalized yet). I was advised by Corvair owners on the Corvair forum that injecting water or a mix of water and ethanol in the intake would greatly help keeping the heads cooler and would also enhance performance.
There you are John. Thanks for your interest.
