billet 67 discussion

Jasjamz, did your billet 67 come in the H cover & .85 housing also?

KevinB,

This thread may be of interest to you. This guy has the fastest time I have seen posted on this board with the billet wheel 6765, but he is running 33psi. 10.62 @128 I think the stock cam is really holding him back with the rest of his combo. The mph isnt where I would expect it to be, but who knows with the right cam??

Im still on the fence.

Yes it did. Ported shroud too. I just got out of it. I will have more testing done in a week or so.

Thanks guys!
I had a few set backs getting my old tsm engine back together. My 4 year old gn1s are requiring a few $$ to be thrown at them before the engine goes back in the car. I can't complain because I have put them through hell lol. It didn't help that a broken key let the exhaust valves kiss the pistons haha. Anyways, my new Turbo will be bought over the winter. I'm watching 2 cars that have the Turbo I want. One of them I'm the wrench Turner on and Cal and rpe are going to make the HP. I have a feeling I will see what these billet turbos can do when pushed.

Kevin,

I wish I could help you out more... I've personally owned/built/installed cars with one/some of the following:

Limit Engineering Te45a (most were Q-trim, some P-trim)
Limit Engineering Ta66 Q-trim
Limit Engineering GT67 Q-trim

If you search on the board here you'll see where I got a local guy one of the very first billet 6768 turbos.

K.

Keith me or u got the first 6768 dbb billet im not sure who got it first.
Im sure i was the first to put a 70GTQ dbb on a TTA

I blew a hg on my stock long block GN with the 6768.. it felt like it has a 10.60 in it atleast with stock longblock .. Went a 10.90's and would barley spin the tires in the burnout box lol. the converter was way to tight

Well, tried again yesterday. Had the boost spike to 31 psi then fell to 27 all in 1st gear. In second, 27 and third it stayed at 29psi. A/F avg 10.8. IAT 142 before it was hit with methanol from an m10 & m15. Timing 25/23. 110 in the tank. Going to try an open dump pipe and a few other thing next weekend. This run matched the 70 GTQ at 22-23 psi. It does spool to from 10 to 30 Psi in exactly one second though on 17* of timing says the powerlogger. I will post the two runs later.

The first was right off the trailer and rather dull. Boost was 25-27psi and timing was 23/21. Same a/f and IAT was 131 before the meth.

Are these IATs normal for that boost and a CAS V2 FMIC?

why only 17 deg of timing during spoolup?

 

[jasjamz]

OK, Doc, two answers for that.
The chip has that function for pump gas and alky cars to avoid transitional knock retard. I may have logs with it off. Gotta check to see if I do.

The other answer is, that's you and Turbocliffs chance to get a head start before I prepare to do punish you both at the last southside meet. Oh and I tried to like up a battle with The popular Z06 from the local road...he declined! I will fully understand if Tom J and I have caused Betty to come down with stage fright.

Ok, this Turbo needs good heads and an all around good combo to perform. Just saw the difference between this Turbo bolted to a built engine and a stocker. Same car, same Turbo, totally different combos, very different results. I believe this Turbo may not be the magic piece on your stock engine....but an engine with the right parts will yield good results. Looks like I am going to have to start saving

If you don't mind me asking what type of combo would you do to accomplish your goal (Cam & Heads) now that you have seen what it will take? I know all other things would have to be up to par (Injectors, Fuel Pumps, Convertor, ECU, Suspension, etc, etc...)

Thanks,

Thats my friends car and umm yea he blowed it up about 2 weeks ago... It was running consistent 10.50s but he was running 35psi( no alky on e85) to do it...It didnt detonate it broke a piston he was using the stock untouched shortblock though!!!

I plan to bring my street car with this turbo to BG this year instead of the race car. It has all the supporting parts needed to get the most of of this turbo - roller cam, good heads, etc. It ran 10.88 @ 125+ in the 1/4 the first time out of the footbrake on a real soft launch with low boost and 20-21 deg timing - there's plenty left. I've never gotten the time to spend at the track with this car to sort things out so this is my chance to beat the balls off of it. I plan to do a little experimenting with different exhaust housings if time allows. :biggrin:

 

[2QUICK2B6]

I Think i got something in a box to make this turbo wake up

 

[SloGN]

ok i think i can play here too!


I recently purchased a billet 67hpq DBB with the small cover 3x2 inleet/outlet.

Before i bolted this turbo on i had run a best of 6.76 with a 1.54 60ft @102.77 @ 20 psi down most of the track and it creeped to 22psi for like the last 50 feet. This was acheived on a 5yr old gt6152e turbo. the outside temps were in the low 60's. timing on this run was @ 24 degrees.


Now this past weekend i went back out to the track to test the new billet 67 hpq dbb turbo.

My first run was @ 13.5-14psi boost. it managed to run a 7.26 @97 mph with a crappy 1.70 60ft.

My next run was a 17.5-18 psi boost. it managed to run a 6.93 @101 mph with a 1.65 60ft

The last run of the day was at the same boost 17.5-18psi . it managed to run a 6.83 @101.5 mph with a 1.57 60ft.

The outside temps were in the low 80's.

All the runs were made with 22 degrees of timing!

The car weight is a tad over 3660!


The engine is a girdled and stroked 109 with diamond pistons dls roller cam ported ta alum heads roller rockers ported stock intake chinese headers. fast xfi

The V2 FMIC wasn't intended for high cfm turbos like the Billet 67, which is why Tony made the V1 FMIC. But with twin Meth injection, that's not a big deal anymore. FWIW, Cottons FMIC has a better pressure drop which is a bigger deal when running a huge turbo at close to 30psi since you can make up for any lack of heat transfer with the Meth.

The turbo does not determine the cfm an engine uses. The displacement and rpm do. Its possible that his engine outflows the v2 but i doubt it.

 

[GNVYUS 1]

I think there was a big turbo V1 that posted a low 110 IAT temp from a track outing years ago. Tony knew his stuff and made the V1 for those turbos. But with Meth it comes down to core backpressure IMO now.

The v1 has been in the low 8's at full weight. With meth your definitley right on target. The core doesnt men much unless it causes a big pressure drop.

What sort of pressure drop are you seeing? I have never tested this one.
