Billet 67 runs 9.71

THS will be interesting. I know of another car that will run good:biggrin: Not mine though

What we need to take from this thread is the capability of the turbo.....nothing more.

It doesn't matter if it's a stroker or stock stroke. The turbo is capable of 9.70's on any motor. Cal could list everything this car has and I guarantee people could copy it down to the T and only run 10.50 if they aren't on their game. Every detail has to be gone over to get the car to work, get the right boost curve in it, get the proper valve springs and valvetrain for the boost level and rpm range. This is why paying someone like Dan or RPE to build a motor program is worth the $$$$. It's all about the details.

What should be learned from all of this is if your wanting to go mid 10's......you don't need a 67mm. Put something smaller on it to help with spool-up and driveability. If you can't go mid 10's with a new 62mm.......something is wrong and it's not the turbo.

Nuf said.........

I'm now a believer. Sometimes I just need to see something happen in front of me.

Elaborate please.

Its still nice to know it has more left in it..Even if you buy it and dont use it to its max potential and it also shows that whatever is wrong with your combo its not your turbo so it forces you to work harder at getting things right...

Hmm - I see you've changed you're tune about this turbo. I said this was a 9 sec capable turbo over a year ago.

I said it then and I'll say it again now - it's a 9 sec turbo with the proper combination and in the hands of a good tuner. A lot of folks will get this turbo and be lucky to crack the 10s. It needs a good cam and heads to see the real benefits.

I'm kinda waiting to see if any of these show up in TSM...... wouldn't that be someting to ponder...........I do think however.....it would likely require the 4 bolt version though to have a shot in TSM to be competitive.

Not trying to be an A-hole but since you asked - remember the thread I started back in early 2009 when the billet 67s first came out?

I will be the first to agree that it's not a "bolt-on magic 9sec turbo" but it can get the job done with the proper combination as we see here in this thread. This guy's supposedly doing it at 3800# to boot. You are right though - it's not an easy chore and there are certainly better/easier choices out there if 9's are the goal.

Like I said Bison, I don't mean to come across wrong. I agree with what you're saying and with the fact that we don't have enough information to make much out of this guy's combo. Reading though this would lead one to believe the car is THS legal with a compressor cover change. After my earlier post today, I was informed that this is a T4 flanged turbo so that changes things a bit. The 3800#s is a bit questionable - not many TRs that heavy. The billet 67s are probably capable of 35# plus and the real power isn't there until 25# or so.

Since I'm probably just going to be farting around with my street car at BG this year, I may just have to be one of the few with the nuts to crank one up. I didn't really build the current engine or go with the billet 6765 with intentions of running 9's - it definitely has a low 10 in it but I may just have to crank it to 30#s and see what happens. I ain't skeered................:biggrin:

I wasn't at the Nats. Did this car show up???

If he did, he didn't race ths. We had the trophy ready and all lol

Someone did go 9.90 in ths though from what I read. Thats cool!
