In case you didn't read my main thread on the project...

Yes, the special L67 parts were bolt-up to the LN3. No special fabrication. I visited Ryan of GMtuners/Sinister Performance and he did the tuning, and he said that performance should be close to what a stock Series 1 L67 at around 220 hp.

Most my posting was at the Reatta.net board, but I came here since I figured you LN3 guys would really be interested in this. Swapping the entire L67 in (I bought one) may have been better for long term durability but I'm not really worried about it. Hal/2seater at the Reatta board has a turbo LN3 pulling like 260-280 hp, so it can't be that bad on mine.

Lots of details on this project, but I'm happy with how it turned out.

I am planning on trying it out at a track sometime this summer. Not sure what older Bonnevilles weigh but my Reatta is around 3400 lbs, so you can compare performance. The parts are stock except for a cheap APC ricer cone filter. Can equally be done to an L27 too (Greg Ross on the Reatta board has done it).

Be careful with that comparison. It'* apples and oranges. Turbos don't make the bottom end torque that a supercharger will. This puts ALOT more strain on the drivetrain when launching.

You cannot make this somewhat basic-sounding comparison. The supercharged motor is gong to be alot harder on the trans than a turbo ever would.

oh god that 4t60e-nonhd LOVES YOU LOL.


however if you take it easy when you launch and avoid burnouts that thing might hold up for a while

That is too cool though, it seems almost as fast as my ssei, did you open up the exhaust and intake and such already?

Hearing a LN3 whine - priceless.

Which reminds me...I have an 89 SSE with and LN3 sitting around...

BTW, someone has to find a way to rig up that computer in a Bonneville.
