I'm still on the fence on whether to get this turbo or go for something bigger, like ef2.5. Would be interested to see your e85 numbers. I'd really love to see ~400 dynojet on e85. That would help me make up my mind pretty easily

Has anyone done 1/4 mile on one of these yet?

 

Mine made 335 on dynojet on stock fuel system. E85 setup it would easily hit 380 390. No launch control sucks for the ra 1/4 mile times. I ran a 13.0 @ 110 without launching it at all, just used sport mode and gas pedal lmao

 

Thanks Chad! I'm planning on getting LC on mine soon. A friend of mine has broken into the 12's on his stock turbo (e85, S-Sport), so I'm hoping for low 12's when I upgrade my turbo.

 

I was the first one to own the rad full turbo. With the right bolt ons to include injectors and new fuel pump, E85 and tune you can achieve what your asking. However without upgraded clutches you will not be able to maintain that high level of power on the SST for long before something fails. Keep in mind the stock clutches are rated at 350 TQ. Do some people run more than that yes they do. However if this is your DD and the only form of transportation you have I would keep the power level at 300 or less until you do a trans upgrade. Also keep in mind 400 Whp means your at or above 500 at the crank. Our engine is rated at 500 crank HP on stock internals . If you want high HP that will last you better plan on dropping a wad of money to be a part of that crowd. Just things to keep in mind. When you pass that 350 benchmark on our cars things get ridiculous. Can it be done and be reliable yea absolutely but not without a heavy amount of money. Just my 2 cents from what I have seen people deal with

 

It is very likely that I'll be upgrading my clutch packs in the next few months, so I'm not too worried about that. I thought that stock block could handle a bit more, but I guess it's always a gray area that I don't need to push my DD into... 400 is a good number though, if I can reach it

 

Stock block isnt the problem with the 4b11. Its the **** rod bolts. They snap at or over 400whp. In my opinion e85 setup isnt worth it. Pain in the *** and too many failures can happen. Use your fuel system setup you were taliking about and tune it on 93 oct. It should be near 350 whp. Have the sst tuned also, helps a **** ton with stock clutches. Keep your tq levels down around 330 at most. You wont have any issues there with a good tune. My buddy derek has a 12 evo x gsr with bolt ons and a tune with same company as my ra pulls 2 cars on it and his made a little more power on the dyno (sst tune!)

Just wondering if everyone was tuned on 93? I would imagine so but I am wondering as I only have access to 91
