I already have a good pipe atleast I thought is was. It's an RB lsr 2-1, but i think this pipe is made for larger cu in motors. It only picked up 2 tq and 2.5 hp over my python III's which is where the real disappointment is, it might have been different if I went with Scott's suggestion on the Supertrapp. I do plan on hooking up with a tuner here on the island before I do anything and go from there. By getting another look at it on a dyno I might be able to get what I'm looking for.

The super trap will get what you want due to adjustable back pressure vs. a "canned" system set up for parameters that are probably different than what you have.

It will also allow you to move the peaks to different rpm ranges as well as give you options such as more torque and less horsepower or vice versa.

The amount of disks you use may affect how you tube. Yeah u can potentially end up with 105-110 depending on how negatively your current exhaust is affecting your results.

I would also do a compression test to see how much cranking pressure each cylinder is making. Static ratios are mostly irrelevant. Cranking pressure is what is important. Compression test will only cost you time and is easy to do.

Speaking of which I want to test the compression of mine out of curiosity since I am so happy with my ridiculously smooth Evo.

In all due respect, a 80" isn't going to reach 110 unless jumping into the world of Redshift 640's or Woods custom 9 series with a whole bunch of compression, street manors will become poor. I"m a fan of the little engine that could but sometimes it is just best to get a big engine and give in to reality.

Like I was babbling earlier, that 3 hp will most likely cost $500 plus but that is the cost of any performance once the bolt on items bottom out and re engineering takes over. Personally the 97-97 with a W8 is great numbers for a 80" hey, it is safe to we have spent more on items that mean less to us.

I would do a compression test that is low for your build at 10.8:1 static with a W8 cam your CCCP would be around 202 lb
at 195 your compression ratio is 10.45:1 and there's your problem


my build with a W9 cam 203.1 CCCP 10.97:1 static and 9.63:1 corrected

Is his engine 80" or is it a bit more? I am thinking that he already has excellent numbers that it might be a little larger and may have had head work done.

I know that 110 hp is difficult without going all out. I was just trying to make a point that a properly tuned exhaust system along with adjustments to fuel can potentially take him to 100 or beyond since he is already at 97, especially if he has a crappy exhaust or it is improper for the rest of his setup.

HP is a product of torque - and the speed of torque is the real deal not how much HP on a dyno that can be manipulated to show any number the operator wants
