Before I can answer you HP question, next time I go to the junkyard, I will rip apart a Bonneville of your year and take a look at the engine design and I can give you a better idea. I need to see how the heads/intake manifolds/exhaust are setup up to get a better idea. I will just rip apart the motor, it will take me like 20 minutes and I will have a better idea.

Good luck in ripping apart a Bonne at the wrecker yard. Any info that you can get from it will be really helpful.

Will...I was all ready to go check the diameter and circumference of the TB...but, freezing rain outside!! Damn!!!

I just got my hydraulic hood supports installed....as well as $1200 of other work...

When you can, or anyone else. We'll need this infor by the time I test fit the Series 1 in my car. Hector will need to know if the Pre-92 is the same before he goes into production on these.

Thanks!

Don't forget, or I'll hunt you down, and you can't go fast enough to get away from me!

94 TB is different fromt the 93. I'd buy 87-93 being the same size, though. Thanks. Just need to make sure the TB size is the same, and that there'* the same amount of room for the cone and the bend in the pipe.

That sounds about right...I did mine in metric tho...8.255 cm inner diameter.

I did a circumference check on mine. About 8-1/4" or 21 cm

WIll this work?...did I do the math right, architects actually suck at math...

Ok, what we really need now is the amount of space to get the cone as close to the back of the headlight as possible. If Hector is gonna find one at the junkyard, we're hooked up. This good enough for you Hector?

I have a feeling the TB is 3 1/2 inch around. Any smaller would choke the 3800 engine. I can double check at the junkyard later this week. Thanks for you help guys.
