Any idea which long tubes they are running? I'm curious to find out if there is any power difference good or bad with the 2" primaries. And if so at what point.

Does your exhaust neck down from the mid pipe to the H or X pipe at the slip in flanges.

I have this current setup that’s tuned by Alex at Lund. He has me capped at 22* since I only have OPG/CS. I have 1 7/8” catless Texas Speed long tubes and a Krona catback. Got rid of the bottle neck so it’s full 3” all the way thru. On a dynojet last Oct I put down 821/613 STD correction. The first run with the 808whp was the same setup just the first pull. 821whp was the second pull.

I’m curious about the 2” primaries as well. The only thing I’ve seen was a recent VMP video with a guy who just put some 2” LTH on his GT500. I believe he’s over 1000whp. I’ll link the video. He said increasing to the 2” supposedly dropped boost levels by 1psi. It’s obviously a product placement video so take what you want from the info.

(Just for reference, on the same dyno on 93 with the same fuel system I was capped at 18* and running the 3.625” pulley it put down 726/565 STD correction.)

I"m not on e85, but I made 767 with 93 and Boostane on a 3.5. I'm sure there is another 30ish on the table with e85.

What other mods did you have with the whipple when you made 725 on pump?

Nothing else different than what I listed that I currently have on the car. It was tuned by Alex at Lund for that setup as well. 3.625” pulley and 93 with lower timing. I wanna say I had the stock PP wheels/tires on the car for the dyno so I wouldn’t have my drag radials on the dyno.

Dyno graph with 93 fuel and 3.625”
Both of these graphs are in STD correction so they’re a bit higher than what SAE would have shown.

All these responses are right in the ball park. I did 788/593 on 3.5 and e85 Lund tune. Dips in power were from belt slips. Replaced belt with the correct sized normal RPM belt as per whipples new guide and no more slip. I just don't have the follow up run to take a picture of.
