Just curious if there are any larger throttle bodies available. The BBK 80mm is the biggest I know of. I have an 85mm lid and maf and feel a larger throttle body would help out. I also have a sheetmetal intake that can be ported to match.

TPI makes one. TByrne has it check their site.

Actually, it won't make a difference how big it is because the size of the hole on the intake manifold will be smaller than the throttle body's.

You're better off just porting/polishing your stock one and doing the bump stop mod.

What he said.....

The intake is 75mm or so, so anything larger than the 80mm BBK would be a real pain to match the intake to (if even possible). I was able to take a grinder and port the intake opening out to match the 80mm. I didn't quite get it out to 80mm's but I got it close (78mms or so). It no longer whistles and I sware I noticed a nice jump in performance over the stock unit (could be the same amount of performance as a ported stock unit but I don't know....).

I have a sheetmetal intake with lots of room for port matching. I think a larger throttle body would be beneficial for my setup.

Yikes. $650 for a throttle body. It does look like a nice unit and sound like it makes good power though.
