MPI or TBI ?
I think when I do go to Fuel Injection, I'll go with a TPI
Well Tuned Port Injection is simalar to Multi Port Injection as long as it's not Cross Fire Injection!
I was thinking the kind GM used on the V-8 Camaro's in the mid/late 80's. I know the V-6 version had crossfire
V-8 Cross Fire in Camaro & Corvette!
I am refering to Trottle Body Injection(TBI) or Multi Port Injection(MPI or TPI).
I want 85 camaro style multi port injection for my /forums/images/graemlins/k5.gif

Multiport is the best way to go, however a lot has to be designed into the system such as runner length and the design of the rest of the system, also it has to be matched with the cam correctly in order to take advantage of intake tuning. If it is improperly matched it will run poorly. Tbi is nice b/c it is simple and it is cheap. BTw I think that crossfire was a tbi system. The manifold runners were what overlapped butit ran like crap, my dad had it on his 84 vette.
MPI in the form of TPI for sure.............just my biased opinion of course. TBI is less expensive tho............. /forums/images/graemlins/thumb.gif
I like TBI for it's simplicity, easy of tuning, and the MAP sensor as opposed to a MAF $en$or.
TPI with MAP is the hot ticket...............anything after 89 is MAP............. /forums/images/graemlins/thumb.gif
Can you confirm, the MAP sensor is the little sensor that gets a vacuum line, while MAF is the hot-wire in the intake air setup... correct?
