Re: How much do these turbo's run (PT70gtQ/3-bolt)?

Don, above, recommends 3600.
 
I wish I still had my LT70 turbo

I call bull**** ...not on the pte turbo numbers but the crappy 72 turbo numbers

I made more than your talking with a p-trim 70 with a little garret housing on it

Im close enough to drive up and witness this if you want to compare sommore turbo's

I know for a fact Harry wont try to line my pocket to say one of his turbo's is so much better

same with cal doing the dyno test on louie's car and showed the pte turbo made more power than the John Craig turbo did but ..proof is proof louie'c car slowed down in et and mph

its starting to be pretty much a yearly plug for pte on here now that their turbo out powered someone elses first was cals testing to out power a John Craig turbo now you guys saying they out power turbonetics

guess it can be over now since that pretty much knocked down the only real competitors that pte has in the buick crowd


I think its real funny that the fastest stock block car right now does not have a pte turbo on it :p

nothing personal to you guys getting paid to type this stuff on here but I call b.s

I and many others do not believe a q-trim 72 bb turbo wouldnt make more than 516 rwhp at 30# boost :confused:

I've had several people talking with me about this thread so figured I'd read it for myself and of course I cant hold back from disagreeing :D

in the next few weeks we'll be dynoing a stock block car with hand ported Irons with a turbonetics P-TRIM 70bb turbo

guess we'll see how crappy a turbonetics turbo really is
I guess if that pte is suppose to make 100 hp more than a q trim 72 then it should be good for 200 hp more than a p trim 70 :confused:
 
I think your comparisons are wrong. :D It was a standard 72-Q if I remember right. This was going against a 70 GTQ (the new style Garrett wheel) which the TSM guys are getting bigger gains with. I wasn't there but know Bill and he wouldn't fudge the numbers or give false reports. I for sure don't think he is in cahoots with PTE! He said the power was made on the exhaust side which makes sense to me. I have seen some stock block cars running 72's and they just don't run as expected. I don't think they have the exhaust to drive them right. Something to it! A white clone of my car goes to the track with a 72, liquid intercooler, yadda yadda and the best I have seen it go is 10.60 puking its brains out. Even with a hurt head gasket and a little P-trim I snapped an 11.40@ 17 PSI and look what you did. What is the fastest you have seen a 72 stock block car go?

That is exactly what happened, PTE called me and offered me enough money to retire on if I would post a batch of BS about how great their product is because it certainly doesnt speak for itself. The fact that I am a distributor for Turbonetics as well has nothing to do with it either. As you said, you live close enough, bring your car in question with the TNetics 72 to my dyno and I'll run mine with the 70GTQ, we'll each put up a "couple bucks" make 2 pulls each and the winner takes it all......that aint no BS!

WOW!!!:o
 
I guess the 70 GTQ from PTE is not rated properly. A 9.46 @141.3 at 26psi WITH a 3 bolt .85 precision housing. As Bill says, the thing ROCKS!

PTE did send me a check to say the above too..



P.S. The engine builder installed Fel-pro 1000 gaskets on a 4.020 bore motor + the chamfer of the bore factored in with about 20 runs = massive blowout between #4, and #6 cylinders and all cylinders showed leakage between bores because the fire ring sucked down in the bore when they were torqued, so maybe some 9.3x's are in the future.

I would like to try one on my stock block, will it make more power then my John Craig 76 gtq? Highly unlikely.
But since PTE is sending out cheques and retirement offers i hope they will send one for free, and i will post back the results.


;) :)

516 does seem a little low for a 72. I made 521 rwhp with a rich setup (10:1 AF)and 24 PSI. Then I went 10.42@130 with 1.52 60' in a 3620# car @28 PSI. All with a much smaller TE-45A.

They say Combo is everything and maybe the 72 was too big for the combo it was on and the smaller gtq70 matched it better and brought the combo alive. If I dynoed my car with 45A and then just bolted a t-88 to it and made less HP than the TE-45a, would that mean that the TE-45A is a better turbo capable of making more HP than an 88? I think not.

If the car was only making 516 with a 72 then I would think some thing may be wrong with the combo on the 72. My numbers lead me to believe my 45A is making about the same RWHP you got with the GTQ-70.

The test I want to see is if you would have actually made any more HP above the 24 PSI. From what I am hearing, the GTs may drop off above 24 PSI a lot worse than a regular t-series turbo.

at least that is my .02

That is interesting considering they use the same Garrett wheels. Was the PTE turbo ported? That is about the only thing that could make more horsepower.

Are you sure that they were the same turbos? If they were, they had the same wheels and housings, the only other thing could be the porting.:confused:

That should read something may be wrong with combo not someone.

Stupid not allowing editing of posts.

You are correct. The port shroud housings are Schwitzer units and PTE seems to like to use them.
 
The reason for my car to "slow" down if based on my performance at the Bradenton event, was due to a new converter I was using /experimenting with.This converter will spooled like mad , but slipped about 18% in my car.

Bradenton was the 1st time at the track with the new turbo after the dyno test. I was rather happy with the performance considering the added slip and air temperatures. Anyone that watches and listens to the Bradenton runs(MPEG) can hear it at the shifts.Even with the extra slip i didnt have to run high boost during the whole event. The car ran a 10.28 at 128-129 on 22 psi in its 1st pass off the trailer.

The converter used on all dyno runs and my 9.98 run had about 11%. This was the converter that i ran at BG during the" big wheelie". If you watch that video you can take a nap and wake up before the car begins to spool. This converter was just not cutting it and cost me at least 1 race.


I have since had the converter restalled and from the limiter runs i got at BG it looks very promising.

Ted, 9.30's from the Precision 3 bolt 70gtq shouldn't be a problem. I have not heard of another turbo mfg 70 series coming close to Precisions numbers. The choice is clear PT70 gtq=Big HP
the other guys 70 series=average HP.
 
When I made my initial post, I made it with the intention of providing information, I was not trying to sell anything, I do not pay to advertise on this board or any other for that matter. I thought it was a neat test and wanted to share my results. I bet if you asked my customer if he'd be interested in swapping back, he'd be sure to tell you what he thought of his 72!
