Somebody at BNR should donate a couple bucks to someone with a 2871 and someone with a 2860.. The no numbers isn't helping your sales!

Well took the car to the track. First run was not good at 15.0 at 110 got wheel hop at the top of first so i let off. Second run was a 13.7 at 109 still wheel hop top of first but just put the clutch in this time. Thrid run was 13.5 at 114. Same as other kit but i was only seeing 24psi on this turbo. It been a long time sence i been to the track so i a little rusty.

Only 4mph higher than a stock turbo car? I was expecting more like 117-120mph trap. Need more practice maybe?

Hey iboost, you enjoying Hawaii? I was living out there for 5 years, just moved to Cali in December. Let me just say, you'll be a rare site. Back in 08 when I had Ron Burgundy I was one of 2 SS/TC on the island. There are a few more now but I think I can count them with my fingers still. H3!!! Baby!!!!

I lived in Waikiki. Go to the Nex(the front, not the back) on Fridays. My friends would love to see you SS.

UPDATE
My car didnt like the blend and bigger turbo for some reason. It would be fine for a while and then the trims would swing and start the part throttle kr again. It was fine on the blend and stock k04. Anyways, I decided to go back to 93 at stockish settings with the 2860 and shes real happy now. Im slowly adding timing and boost until it starts to kr again and then will back it off a bit. Ill probably run full E on it once Vince releases the full E tune to me. I should be dynoing here soon Get some stockish numbers on 93 and then dyno again on full E later on in the year, but so far so good finally.

lol.. I'd love to test it myself but unfortunately I'm as broke as a joke brotha.

So wait, you're telling me you spent the money to do a freakin turbo upgrade and now you're throwing in the towel at the finish line due to an extra $80?!? Come now you must be joking.. Just on principle alone I wouldn't send you the $80..

Those of us who have one running correctly already know the results without a dyno graph, yes its thats noticeable with the GT2871. I'm running the exact same amount of boost I was running on my KO4 with the BNR GT2871, 26 psi, the difference is very noticeable.

By the way I didn't throw the towel in on ****, my car runs awesome. I never had a problem with the BNR turbo from the get go, installed it, started it up and ran, no leaks what so ever, the only problem I initially had was getting the BOV set up correctly, but thats not BNR's problem. It was mine and I fixed it.

I've been driving my GT2871 around for 3 weeks at 26psi, trouble free with a huge ass grin on my face.
who tuned you?

You have to datalog with any tuner, no tune is "good from the get go"

Vince did say that he could unleash even more power once I get a clutch install. (maybe he was talking about how fast it ramps up do to the factory clutch))
I don't know what kind of difference that would make in dyno numbers.

Rattling my mouth? Dude take a deep breath and relax a bit. It's called playfully busting you ***** because no one has posted dyno numbers. I personally have no real intentions of ever buying the kit, it's purely out of curiousity of how well the hybrid performs (along with MANY other members in the forum who would like solid numbers.) So there's no need for the long defensive rant you got goin on here. I know sarcasm and ball busting can be hard to pick up on here, but sheesh.. :P
