Trackspeed Engineering EFR6258 kit with "Medium" waste gate actuator
Another dyno from Bullet. Stock BP4W head, ST double valve springs, forged internals, squaretop, 3" exhaust, E85. 23-25psi Low line is the map from the last Supermiata event we ran at ACS, 220whp. This is our spare motor for UTCC/Hyperfest in a few weeks. We'll swap in a whammy engine, +2 CNC BP6D head, cams, coatings, etc. That one should make another 30-50whp we think. https://cimg7.ibsrv.net/gimg/www.mia...809f7dc6ec.jpg |

I have to give huge props to Andrew on this kit, first event out and my co-driver not only won our class, but set the fastest time of any street legal car, even those on Hoosiers. We were on 245 Maxxis VR-1s. We never turned a wrench and only fiddled with tire pressure...what an amazing kit! Car was running 8 lbs. of boost on E85 with the 6758 EFR to stay below our classes 9:1 weight to power ratio.
FYI...I run the Flyin' Miata silicon intercooler piping and it works beautifully with the TSE kit for those waiting for a final solution. I run the Treadstone TR6 intercooler with the inlet and outlet towards the bottom of the intercooler, I don't think the FM pipes would work with an intercooler with the inlet and outlet in the middle. https://cimg5.ibsrv.net/gimg/www.mia...f2f76e4d0d.jpg https://cimg3.ibsrv.net/gimg/www.mia...c75d6bdca0.jpg |
Edit.

Gents, respectfully, please start another thread to discuss using FM's piping. Our piping kit will be out shortly and I don't want to confuse anyone who reads this in the future.

Based on what I’ve seen when porting heads + cams I’d be surprised if it’s less than 425-450 at the same boost level. You’ll pick up some torque but most will come from HP gains as the torque curve stays flatter. Look forward to seeing these results. |

Turns out Vegas' BP6D long block has stock cams. Got it confused with OGK's motor. All the other bells and whistles though. Still thinking 420 or so. Should be able to dyno next Tuesday.

Sav - I've been trying to get a hold of you via email/calls for about a week now. Please shoot me a call or email when able.

If you're waiting on a call or email, I should be caught up by the end of today. I was out Thursday/Friday of last week.

YES!!
Well done. Excellent demonstration of what moar head flow and vvt can accomplish |
Holy shit.

It's easy to lose sight of just how freaky this turbo is. This is the same turbo we're using on all the S1 cars (Bullet included) and they spool instantly. Like, better response than a GT2554R above 3500rpm. The whole focus of the kit, in fact, was on optimizing that spool. We knew they would make the power on top regardless, but god damn. 400whp from the smallest turbo available.
So wild. :party: |
Those numbers are just so friggin wild!!
I'm building an HPDE car, not a race car, and I've been eyeing this kit for awhile. Is there any chance a version of this will go out for CARB approval (when a full kit is finally developed)? I would LOVE to have a street legal track car with this turbo kit, but living in CA really puts a damper on certain go-fast bits. I would happily pay the premium for this kit vs something like FM if it was offered with an EO sticker. Just wanna let you know Savington there's demand, and I guarantee I will put my money where my mouth is. lol :skid: Keep up the great work! -Bret |
All you gotta do is take it to that guy bobs friend to smog it, slide him couple hundo and walah! Your EFR miata can now drive on the street.
|
Until you get pulled over street tuning and they crush your car.
|
nah. they will just state ref you. So spend a day or 2 converting back to stock and then add all the go fast parts back on.
|
Wow.. maybe I should go E85. What do you reckon that same setup will do without the VVT?
