400hp on pump gas - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I was making 366hp/278tq at 16psi prior using a manual boost controller. I felt like I was getting some inconsistent boost sometimes, so I switched to a COBB 3 port electric boost solenoid. This allows for the ECU to control the boost, and in turn allowing for different levels of boost on different maps. The boost also builds a little quicker now.

Currently,
Map 1: ~7psi, 267hp / 204tq
Map 2: ~21psi, 412hp / 308tq

Garrett T3/T4 .60 trim
UEL manifold
2.5" exhaust

It starts building boost around 3-3.5k. It hits 10psi by 4k, 20psi by 5k.

R/T Tuning (vendor here) in PA has done all the tuning and worked out a lot of the hiccups associated with this setup. I can't say enough good things about these guys. They kick ass.

The weather isn't letting me really drive it hard since the pavement is so cold. I made a couple pulls in 5th gear (where I had some traction) and to say it is fast would be an understatement..

I am building a shortblock this summer so that I can run more boost more safely. Hopefully some well tested cams will be out by then so I can play with them as well.
Obviously this is pushing it with these motors. (21psi, pump gas, 400hp, stock internals...)

enjoy sir!

Impressive is all i can say

Awesome!

Sweet, I don't have e85 here so it's great to see someone else staying on pump! What compression are you going with on the built block?

I haven't made my mind up. To be honest, I want to stay as high of compression as possible. I will probably just bump it down a little bit, maybe 11.5. The bigger reason for building it is the switch to forged pistons/rods.

My "goal" is to have a powerband of somewhere in the range of 5-8k rpm and hit at least 500hp on pump gas. Obviously lots of changes will be happening to her for that to happen.

Occam's Razor if I may say so.

How long will the block last with 21psi on 98(RON) 93(AKI)?

No idea. There hasn't been a lot of testing at high boost on these stock motors with pump gas.

The direct infection helps with keeping things cool inside. No knock at 21psi at 12.5:1 is pretty good I think. As far as how the stock cast pistons hold up...

JerryMichaels7 · 03-03-2014, 10:00 PM

this is 93??

Zach3794 · 03-03-2014, 10:01 PM

You know, JE makes 13.5:1 pistons in any size you need. No need to lower the compression. If anything you can slap those suckers in, dial down boost, and still make more power.
