First gt42/rb26 dyno numbers...

Guys

 

I got a chance to hop on the dyno and works some bugs out of the base-map that AEM provides with their software. I am not confident that I'm squeezing every ounce of power out of this setup, however I know its safe and at this point, I'd feel comforatable pulling the motor to swap to the forged goodies.

 

We made 485rwhp @ 14psi however I didnt capture that dyno graph, the one I did get shows 480rwhp.

 

Mods are:

 

R32 RB26

ARP Headstuds

Tomei 1.2mm 5 Layer HG

Tomei Type-A Poncams

Full-Race Twin-Scroll Manifold

GT4202-74mm 1.28A/R hotside

(2) Tial 44mm W-gates

Tial 50mm BOV

Ebay 24x12x4 FMIC

3" IC Piping

4" Exhaust

Stock Ignition

AEM EMS

RC 1000cc Injectors

Dual walbro 255 Pumps

Jgy modified fuel rail (dual -8 feed, single -6 return)

Aeromotive 1:1FPR

I am not sure if the Mic was having problems or what but there is a little crackling in some of the vids, so dont interpret the cracking as the car stuttering, its definately the camera!

wow, I still can't get over how big your turbo is sitting in your engine bay. The RB looks nice and like it belongs there.

 

Congrats on the #s and can't wait till you step it up and push the turbo to what it's really capable of.

Sounds great!!

That GT42 is not even in it's happy place yet ;)

 

I know, thats what I keep telling people, I cant wait!

 

By the way your car is purely badass, I still have the vid of it on the strip saved to my desktop for aspiration ;) I will be going to a th400 sometime soon

Thought of using a 4L80E or 6L80E? You'd save alot of gas with the overdrive.

 

I am not confident that I'm squeezing every ounce of power out of this setup, however I know its safe and at this point, I'd feel comforatable pulling the motor to swap to the forged goodies.

 

Curious, but why didn't you put the forged in the first time around?

Going for forged pistons, rods, crank? What all? I had the impression that the RB26 bottom end is quite tough.

4L80E is big and heavy, lots of power loss compared to a th400 setup....plus I dont drive the car often at all, so not much need for an OD setup.....

 

Also, I've stated this a few times but I've never tuned on the AEM and its basemap is pretty shitty, so I eliminated the big variable of the engine being good/bad and just put it in there stock. I knew the motor ran good before as it sat, whereas if I put it together with all the forged parts and it wouldnt start, or something like that.......It would have been more of a PITA. Also I didnt want to get into crappy tuning ruining my new engine. Cylinder wall wash and all that jazz, especially with 1000cc injectors could potentially hurt it.

 

Now that I have it tuned well and running good, it theoretically should run exactly the same once I yank the motor out and re-install it. If it doesnt, well then I know right where the problem lies :)
