pretty impressive.....
i would be afraid running such high boost on such a newer car, but then again, you never know how much it can take until it has been broken once.....:D

Nice hp/tq.
What's the stock pressure, 6psi??

"Colder plugs will help prevent detonation". :bullshit:

Running that high of a PSI on a stock block with only race fuel sounds like a recipe for eventual disaster to me. There's a reason why Mazda restricts the boost on that car. :banghead:

Besides, 19 PSI on a T25 is just blowing a lot of hot air - it's very inefficient above 15 PSI. :rolleyes:

EDIT - I just realized the poster is Joe P., himself. I use his MBC on my car, LOL. :D I guess he's willing to push the envelope. :rofl:

In his case, it probably would, seeing as it transfers the heat away from the tip quicker. With a 13:1 a/f, I'd say cold plugs are definately a plus :).

Well at least it's not going to break due to detonation hehe. But yea, 13:1 A/F, turbo way out of efficiency range, I'd hate to see the EGT's on that bad boy.

He can't even get over 15psi at redline. He just gets a low rpm spike to 19psi. Much like what I had with my stock 944 turbo. Boost drops down to like 12psi at our lame elevation.

I have the same boost problem, I get 18 till about 4000, then 16 to redline.

4000rpm is your redline:nut:
