Took him more time to tell us how much his vagina hurt than it would have taken him to just post the necessary info in the first post.

SCH 20? Get that tin foil shit outta here.

U mad, bro?
Youre asking dumbass questions like this is fucking honda-tech and now youre butthurt because you were made fun of.

concealer404 01-28-2014 04:08 PM

Math sounds weird.

If your timing is retarded one degree for every psi of boost, you'd think your timing would be -10 degrees at full boost if you're running 10psi.

Other than that, 200hp give 15hp or take 100hp depending on tune sounds like a pretty reasonable answer.

220-230 would be my guess.

kman456 01-28-2014 04:12 PM

That's why I said total of -8 degrees. retarding 10 degrees robs my power at top end.

kman456 01-28-2014 04:13 PM

Thank you that's right where I wanna be

So you're running 8psi?

kman456 01-28-2014 04:25 PM

OK -1 degree timing from stock for every pound of boost until 8 psi then from 8 psi up it stays -8 because car falls on face if I go past -8 degrees from stock.

concealer404 01-28-2014 04:26 PM

How do i enter that formula into my Excel spreadsheet?

Want to estimate if I'm pushing stock internals too far

2001 vvt bp4w
Turbo garrett .48 AR .62 trim
10psi
550 cc injectors
2.5 downpipe
28x7.5x2.5 fmic

Would you mind posting your AEM FIC cal file? I'm trying to tune my 2002 Miata with a IHI MSM turbo setup. Thanks!

Never mind, didn't read far enough to see you were just fucking with him.
