Anyone ever supercharge a L6 250cid using a centerfugal? Someone mentioned a GM factory blower, but I dig spinners more...the look and all.

I'm thinking of going distributorless (is that even possible with these engines?) so that the centerfugal can take up the space where the HEI is sittin...

I'm runnin' a TBI now and am cool with the juice it's making. Don't want to go back to a carb. Someone suggested switching the ECM for a typhoon ECM. I have to agree with the hometown, any other ideas...

Once the rotating assemb;y is figured out the I6 punched out .040 over turboed should be a beast. The head will be the downfall though!

 

I'm thinking of going aluminum on the cylinder head like these hometowns...not as crazy as them, but more for the street.

This beast is an all aluminum 292 that is bored and stroked to 342cid and mechanically fuel injected. This MONSTER with a turbo would be LOCO!

I doubt the Typhoon ECM would work, considering its a 4.3 v-6 not like the straight 6 motor. Just a thought, it makes sense to me anyways.

 

My original concern was that the Typhoon ECM would drastically read the data from the sensors differently, although the V6 and L6 are very similar in displacement. This L6 is 4.2 Liters. I'm gonna check the firing order, vacuum #'s and the like on the V6, not sure if this will make any difference, but it's part of the research I guess...

Thanks for you input hometown...

 

The only problem I forsee is the firing order and some of the sensors wont have mounting holes in the I6 engine. The I6 by design is better. The cylnder head layout is critical. If you are looking for modest power the stock cylinder ported with bigger valves should do. The crank throws are evenly spaced and better distribute the abuse over the entire main. Good caps are definately in order as well as rods and pistons.

Sounds like a good plan to me. Good luck!

 

A 749 would work just fine. Provided the memcal matched the numbers of cylinders, ei 4 cyl memcal/ 4 popper, 6 cyl memcal 6 cyl, etc. The ECM could care less wether the engine is an inline or V, It doesn't know, or care. What maybe a problem is I dont know of anyone running a 749 with a TBI, but it probibly would work. Mine runs fine on a Eaton blown TPI. Just need to get the drivline done to do some road tuning.
