turbotime

First off HUGE thanks to Joe Simpson at Tempest Racing for tuning my car, I have been up there 4 or 5 times now for tuning in the past 3 months and every time something is wrong with my car and I had to take it home, fix it, come back, found another problem, etc. Well, I finally fixed all the problems! Thanks to JOE for helping me find that huge boost leak

Setup:

B17a1
B16 Head, Omni Springs and Retainers
Revhard Manifold
3" Downpipe and 3" Exhaust with 2.5->3" deleted cat []
Wiseco 9:1 Pistons
Crower Rods
ITR Cams
Drag turbo piping
XS Power 3.5" thick IC
Drag/Turbonetics t3/t4e .63ar, .57trim
Tial 35mm wg
Profec b spec2
tuned on s200b

Ok this was interesting, all these runs were done at 15psi, all we did was add timing and look how much power was gained!


The final low [14] and high [17] graph, we upped the boost to 20 but actually lost power, probably maxed out the turbo and/or the car was pretty hot (we did like 15pulls before we even got to 20psi)


Im very happy with it, next upgrades are going to be a new intake manifold, a 3" testpipe and a gt30

Here are some vids from the dyno, nothing too exciting but eh:

Havent boosted the car on 17 yet cause i wanted to let it cool down before running it hard again, ill let you know how it feels tonight

Turbo-charged

glad things are finally working out. when the car first showed up from the prvious tuner it made 200 horsepower, with the air fuel damn near in the 9's, using 10 tanks of gas to get here. intake manifold, exhaust manifold, and turbocharger should make some large gains.

runs 34 and 35 were at a differnt boost level, 36-38 were at the same.

joes the man. when i was getting my car tuned, my mbc was acting up and not being steady and i think i know why now, i think it was because i didnt clamp down the hose when the mbc plugs inline. i found out it was leaking and it made be spike to 12 psi, so i know it was leaking, im gunna give it another shot though for 10 psi. gunna do some smaller diameter ic piping, hondata intake manifold gasket, a tube for a filter instead of mesh and hopefully see some nice number around 300 using stock map sensor.
so where was this huge leak?

I made a FITV blockoff plate out of some thick aluminum but it bent in the "fab" process so it wasnt 100% flat, when we pressure tested the system it was like wind coming out of the sides of the blockoff lol...

i have a leak in this shittily welded steel ic pipe. instead i just bought a nice kit, which is all aluminum and a smaller diameter which i think would be ideal. i don tthin it was leaking on the dyno because (and joe can probably back me up if he remembers) it was holding 7psi at around 4k up to redline. now it wont even make it to 7psi. thhighest is like 6.7, but it drops off because of the leak and i make that at like 6500. at 4k where i used to have 7, i might have like 1.5-2
