Buick 3.8L with oem supercharger
Anyone done a performance increase, like a chip/etc. ? Did these engines get aluminum heads, like GN's ? Will the this blower support more boost ? Thanks, roverman.

Re: Buick 3.8L with oem supercharger
Art,
Yes you can! These guys [zzperformance.com] have pretty much everything for the 3800 and I have used them for my blower parts. They came with cast iron heads which are different then the N/A 3800 engines. The valve covers are different as well. The blower will indeed support more boost and I went with ZZ perf. modular pulley system which allows you to change pulley sizes without having to press the pulley on/off the blower input shaft. Older 3800's came with GM/Eaton M62 blowers while the latter models came with a GM/Eaton M90. The M90 is a better blower for performance applications and in stock form you can overdrive it up to about 14,000 RPM (blower input shaft speed), after that blower efficiency drops off. Bill |

The M90 made 16psi+ boost on my 215 Olds.

Re: Buick 3.8L with oem supercharger
I had one in my 99 grand prix. I had a smaller pulley, cold air intake, 3" downpipe and a tune. approximately 300 hp.
Car ran 13.8s in the quarter. With better tires possibly could have hit 13.7s. I put 100,000 miles on it and never ever had a mechanical problem with the engine. I considered that motor for my TR6 but went with the lighter LS3 A side note: they sound terrible with loud exhaust. No music, just noise Edited 1 time(s).

Re: Buick SC 3800 in Lotus Super 7
Great ! Do you have a weight for LS3 ? L67 series II is said to weigh 392 lbs.
