E85 tune completed at JM Auto. The car made 301WHP and 394WTQ at 22psi on their dyno. It is known to be low reading, but I'm not sure exactly how it compares to others. The numbers aren't too important to me as long as the trap speeds are there. Overall I'm told this result it inline with other stock turbo + E85 setups they've tuned.





Dyno video.


Car weighs 3460lbs with me and 3/4 tank of fuel.



I looked at some speedo video clips (not from the dyno obviously) to compare against past setups. The 50-100mph time was a best of 6.5s and that was on a 4th gear pull. The turbo is just coming into boost at 50mph in 4th and hold strong up through 100mph. Using 3rd and 4th or even 2nd, 3rd, 4th resulted in slightly slower times due to more shifting.

Speedo video:


Hoping to get some 1/4 mile times this weekend. If I have results I will post an update.

The Black and Gray rim combo looks awesome. Any plans on relocating the intercooler in the future?

PS: Thanks for your work with the switchblade. After a week or so, some things got some wiggle. Going to disassemble to tighten things up to take some of the slop out. Programming went quick and got the key cut at a dealership.

I wouldn't relocate the stock intercooler but I'll likely do a FMIC setup eventually. Let me know if you need anything else with the key and I'll take care of it.

Unfortunately they're almost always out of stock. I had happened to get a used set locally last time. This time I picked up the MAP header (locally made) and had the EWG mod done by FobiaFab (also local). Made things easy for me.

It's still in my garage but I never used it so I have started parting it out and bought this instead. May transfer some parts over but I haven't decided yet.

Max Power @4600? Power seems to be dying off quickly especially with E85.

Very interesting ewg placement. Any reasoning for there verses the up pipe?

Stock turbos generally lack top end. Especially obviously if you push the mid-range peak. But it does seem to be dropping pretty hard up top. Not sure if there's something limiting power.

Much, much easier to access. I hate wastegates on the uppipe.

Seems to me your 20g-xtr setup did the job back in the day. But that would be repeating history...something different planned this time, perhaps??

Great point. What a pita it is messing with a wastegate cramed in on the uppipe.

I love the evolution. After chasing big power with older and lighter bugeye what's the spirit of this car?

Made it to the track yesterday. Terribly long lines and 3-4 hour wait times resulted in only 2 passes (stayed at the track around 9 hours). It was a Sport Compact event so there were 90% street tires and they didn't prep the track. I bogged the first pass and ran a 13, and then spun hard and got sideways the second pass (just before dark) and ended up running a [email protected]

Not quite what I was hoping for but not a bad result considering the conditions and the limited amount of time with the car. I think with a little more time it could be worked down to a very low 12 with this power. The early torque is a lot of fun on the street and the car seems to be running well. And I got it detailed on Saturday so it's looking nice and shiny!

I have some more photos from in the pits and from other photographers that I'll be posting later.

Changing direction and sticking with a street car. Will not be as light or as powerful, but it will be driven a lot more. At least that's the goal.

Yeah, I bought them to put my drag radials on. They were the easiest thing to find that would clear Brembo's. I really like the look as well.

Nice runs. Bit off of that 60' time and you're probably below 12.4. For what it's worth I went last week and had the same experience... waited 3 hours and got one run in. Tried to go again and said F it. Late season trips to the track suck because everybody has the same idea.... One last track day for the year.

Who's taking bets on how far this car gets taken? lol because I may want a piece of that action.

My guess is the stock intake is limiting your power there. Especially on E85. VF turbo's need all the help they can get.
