DriftSquad Posted February 6, 2014 Share Posted February 6, 2014 (edited) Hey guys got a problem my car didn't make the power I think it should have made. Rb25det s1 Gt3076r .63 rear High mount manifold 50mm wast gate with 14psi spring 800cc injectors Bosh 044 fuel pump Turbo smart fpr Upgraded coil packs Greddy copy intake. 3inch straight exhaust Blitz dual solenoid boost controller Microtech Lt12 I only made 296rwhp was the best run of the day at 18 psi Seems low compared to others iv seen on this site? Also I did notice that boost drops off from 18 nearly back to 14 at the top. Fuel and air sitting on about 11.6 . Any thoughts?

ARTZ Posted February 6, 2014 Share Posted February 6, 2014 Wastegate too large and poor control maybe...or restriction somewhere Link to comment https://www.sau.com.au/forums/topic/438770-rb25-gt3076r-mods-made-low-power-on-dyno-tune-why/#findComment-7191556 Share on other sites More sharing options...
Ben C34 Posted February 6, 2014 Share Posted February 6, 2014 What dyno? Do you have the chart? Link to comment https://www.sau.com.au/forums/topic/438770-rb25-gt3076r-mods-made-low-power-on-dyno-tune-why/#findComment-7191568 Share on other sites More sharing options...
scotty nm35 Posted February 6, 2014 Share Posted February 6, 2014 You will need a stiffer spring in the gate imo, and the .63 rear won't be helping things. Can you get us some pics of your setup? Was the exhaust dropped on the dyno?

DriftSquad Posted February 7, 2014 Author Share Posted February 7, 2014 (edited) I didn't get the chart as I was not happy with the tune. Tuning was done at Godzilla motor sport. On his dynonamics awd dyno Edited February 7, 2014 by DriftSquad Link to comment https://www.sau.com.au/forums/topic/438770-rb25-gt3076r-mods-made-low-power-on-dyno-tune-why/#findComment-7191717 Share on other sites More sharing options...
Ben C34 Posted February 7, 2014 Share Posted February 7, 2014 Not happy with the chart is even more reason to get the printout. Can you get him to email it to you?

Dose Pipe Sutututu Posted February 7, 2014 Share Posted February 7, 2014 and tell them to send you the tune file I have a feeling the tune was shit house, also because it's a microtech lt12.. they're so clunky to tune with.. 2x tables to do essentially a single table can do.

DriftSquad Posted February 7, 2014 Author Share Posted February 7, 2014 I'll ask him to email it to me. Marks pretty good tuner. I mean it is a microguess lt12... We had to pull some timing cuz she was pinging on boost. He said he thinks the .63 housing is to small Link to comment https://www.sau.com.au/forums/topic/438770-rb25-gt3076r-mods-made-low-power-on-dyno-tune-why/#findComment-7191778 Share on other sites More sharing options...

zebra Posted February 7, 2014 Share Posted February 7, 2014 .63 hosuing will still go 300rwkws Hell "mafia" made 314 with a .63 IW version on the standard manifold What exhaust manifold is it?

DriftSquad Posted February 7, 2014 Author Share Posted February 7, 2014 (edited) Not sure it's just a stainless manifold with gate mounted to it.

scotty nm35 Posted February 7, 2014 Share Posted February 7, 2014 Not sure it's just a stainless manifold with gate mounted to it. The power I Made is not much better then a standard rb with a tune.. If you had bought a decent standalone and left the FFP, stainless manifold, fpr, boost controller etc off the list, you will have had more money to spend on finding the issue on the dyno.

Sinista32 Posted February 7, 2014 Share Posted February 7, 2014 what said above is don't under estimate OEM, until you reach the limits. Don't buy gear that's unnecessary for the power level wanted Link to comment https://www.sau.com.au/forums/topic/438770-rb25-gt3076r-mods-made-low-power-on-dyno-tune-why/#findComment-7191824 Share on other sites More sharing options...
AngryRB Posted February 7, 2014 Share Posted February 7, 2014 300hp is about 225kw on 14psi and its a 0.6rear, so really its not terrible, maybe the exhaust isn't flowing ( restrictor in muffler etc) so the timing was held back?

ARTZ Posted February 7, 2014 Share Posted February 7, 2014 nah its terrible...a 3076 .63 will make alot more power than that...especially with an external gate... ThAt engine sure does look puurty though Link to comment https://www.sau.com.au/forums/topic/438770-rb25-gt3076r-mods-made-low-power-on-dyno-tune-why/#findComment-7191857 Share on other sites More sharing options...
