Thanks for the update Paul, good spool with that 2560! I wish you could post a log with your DD for a better comparison!
|
i'll try tomorrow. i'm actually letting it sit though since the front pads are so low one started grinding. new are on order.

'94 1.8 (8.8:1 comp), GT2554R w/ 7psi can, Bell S3 manifold, SSSG DP, 3" metal core cat, 3" Enthuza
the equivalent of a 4th gear pull on a 5speed/4.1 car (5th gear in my car). 1750rpm: 1.0psi 1870rpm: 2.1psi 2014rpm: 3.3psi 2478rpm: 5.4psi 2626rpm: 6.1psi 2783rpm: 7.3psi 3004rpm: 9.4psi 3188rpm: 11.0psi 3394rpm: 12.5psi 3601rpm: 14.1psi |

here's what happened when i pulled from 1750rpm 100% tp @ 1750rpm 2000rpm 2.9psi 2200rpm 4.6psi 2500rpm 6.5psi 2700rpm 8.5psi 3000rpm 11.6psi 3200rpm 14.0psi |
Damn. damn damn.
I will datalog my car for sure, but I think the twins can't get to 14psi til after 4000. They make like 5psi really low but then sorta stay there until the revs climb. Anyone want a TT setup? Maybe Mark will buy one of the 1548's. Partial trade for a VVT head? I'll use the stainless absurdflow manifold that I'm making and the 2560 off my subaru. :) I bet artie is getting anxious. |

plus the gutted stock cat....most definitely.
Man, I guess I need to ditch my RB exhaust as well. The T3 spools a tad late, anything quicker would be nice. |
I performed some mild headwork and I gained a touch better spool.....this was with a 2.25" borla exhaust.
http://www.boostedmiata.com/log/headwork_boost.jpg this is no headwork with a MBC compared to headwork with an open wastegate line.... what can clearly tell is the headwork helped spool the turbo a touch earlier....you can also see my boost creep started to appear :) upgraded to a 3" magnaflow....the difference is clear: http://www.boostedmiata.com/logs/hea...comparison.jpg |

I'm seeing 14psi just before 4000rpm in 4th gear. I suspect I'll get a boost a couple 100rpm sooner when I change out my exhaust. right now it is 2 1/4" Spec Miata exhaust with an extra glass pack resonator. Ideal it's not. No fancy EBC, just a ball and spring MBC.
