Rb26 Turbo Upgrade, All Dyno Results

[ido09s]

power shouldn't really change all that much between gears, torque is the only thing that will change when using 4th over 5th

Makes it looks more responsive doesn't it?

[ido09s]

it will, but the end result won't be greatly different. The power figures will be vest similar

Whoops, turbos are infact listed!

[burn4005]

holy cow thats a lot on 2530s! how much boost did you need to hit those numbers on 98 and E85?

[tangomatt]

Boost

E85: 23psi peak, tapering to 22psi at high rpms

98 Ron: 22 psi peak, tapering to 20 psi at high rpm

Did this car used to belong to Mark from Rhemac?

The Borg Warner thread got shut down so I'll post here for those interested.

 

BW EFR 8374

Stock bottom end rb26

256 cams

E85

504kw - 30psi around 4600rpm.

Has another 30-40kw in it. I told him to stop at 30psi due to standard bottom end.

[s2d4]

What was the turbo speed at 30psi on the top end?

Forgot to mention power was made at 20psi

[hybrid_eg]

I've posted this in a separate thread earlier this year. I do have to go back and retune again as brand new power FC boost controller did not work again so we ended up running it on manual boost controller. I will probably dump PFC altogether and try "Link G4 ECU"  plus play with cams/gears--currently set at zero. My main question is, what are some general boost levels that many of you run on your cars? I plan on running this motor regularly at 22-25psi.. car will only be used for couple of monthly coffee meets and occasional evening night rider passes.. along with few drift events each year.

Most importantly, I'm thinking of dumping the brand new GTX3582 for an EFR8374 rear 1/05 a/r divided housing in hopes for quicker spool and more power at the same boost level. Can anyone share their experience with 8374 in comparison to my set up? I hear 700whp should be no problem and that's my ultimate target goal.

Any feedback is greatly appreciated!

Set up is as follows in S13 chassis:

Mildly built R33 (pistons, rods, upgraded oil pump, HG, head studs, tomei poncams type B

ID1000cc injectors running power FC d-jetro

e85 race gas

all the misc bolt-on's you can think off

running GTX3582R, .82 rear T4 undivided with two 50mm gates

Here is what it made at 22-23psi..
