This was done with a simple dry 20 shot before the maf. We couldnt hit the juice until after 5000rpms or it would just spin the clutch. And Im pretty sure thats why the torque wasnt to impressive.

Those runs were both done on the same day. The test run was on the sauce.

What do you guys think?

I cant wait to go back to the track

Again big thanks to Paul from EIP racing.

I guess you figured out the limits of the stock clutch. Nice numbers.. that's an insane amount of power from the stock turbo on a mustang dyno.

wtf, your trq is actually worse, it peaks higher for a split second then drops like a rock. (nevermind I was reading the wrong line. lol)

and about 60whp more for 1300rpm.

Where you monitoring knock and timing at all? what octane fuel? C16 again?

Time for a new clutch.

just curious about the hp@50mph number. do you happen to know
how this is figured? does it come from mustang or is it calculated from
something else.

just asking because i noticed gruppe-s uses 12 instead of 11.80 and i didn't know why these numbers would be different.

Thats funny I thought the same thing about the tq when I first saw the graph.

I used c12 last time but thought c16 would be better for the nitrous. I wanted to use the 40 shot but we knew that the clutch just would handle it.

Paul was monitoring all that good stuff, but I cant comment on that. Maybe Paul will chime in.

I have no idea, maybe someone else here knows what that means?

btw is there a reason why you didn't take it to the rev limiter? I would love to see what your top end looks like.

I take it you don't pull any timing back when you hit the nitrous since you have an safc.

Correct. With c16 and such a small shot Im not worried about the added timing.

The graph shows power is dropping off so we felt no need to rev the car any higher.

But you're still making over 350whp when you let off. I'll take an extra 700rpm of 350whp. 8)

btw... I give you props for messing around with NOS. Not alot of people really try different things. Guess this is your domestic background coming through eh?

Nitrous has always worked well for me on the mustangs and lsx powered cars.

We will see how it works on the evo.
