70 turbos

[Fuelie600]

I don't want to come off as being unfair to Jack cotton who is having one heck of a sale on turbos at the moment, but I would like some comparisons. Apples to apples---P-trim, with equal size exh housings and a 70mm wheel, is there any honest difference between ( turbonetics, Limit, and Precision ) builds. I want to move to a 70, and was thinking of a GT through Limit ( which has always built my turbos ), BUT JACKS PRICES ARE GREAT. I have no experience w/ Turbonetics, so I need educating. Thank you, Brian

Best bet would be to read the existing threads regarding turbo tests and draw your own conclusions.

I doubt there has been a test done between the 2 you have mentioned.

There's not even that much agreement on how to set up and do a valid turbo test comparison.

I'd start with finding someone that runs the CPT70 and get their thoughts.

I made plenty of power (559rwhp/627rwtq), 7 less than Louies car with the "big boy GTQ super turbo" with my regular BB70Q from T-netics. I did it without the help of FAST, 3 1/2" DP/exhaust (did it with a single 3"), external wastegate, co2 assisted boost control, or help from any performance shop. That was my street car........... Turbonetics turbos are the real deal without the hype of GTQ technology...........This car will make more, I only got 4 pulls! I'll keep you posted.

When I get the new Super T-70 Q and bring my race car to the dyno, I'm gonna make a hell of a lot more than that! If I ever get that car done! I suck, I gotta get my a$$ in gear! That car hates me!

Not tryin to start a war here just stating some facts that a regular guy without a magazine article, a shop, or big $ behind him, can do it..................


Big thanks to Steve Y and ME-R! Yea, dude!!!!

If you take Dave Bamford's 142MPH @ 3560Lbs we are talking about around 796RWHP with a PT 70GTQ.
I would love to see some info from when your test your Super T, there is not that much info on these units yet.
Please keep us up to date!

 

[Russ Merritt]

That's why his name is "Top Gun"..........


That's what 249 ci, steel crank, aluminum rodded, super motor will do for ya........... Be cool to see that same article with his car on the dyno tesing differant turbos.........


That is without a doubt, "we're not worthy" performance......


BTW, my race engine will not come close to that as it's only a 235 ci with stock internals....................... Should be fun though......

There's some guy down here with a 234ci 109 that has gone deep in the 9's (9.57 @142 with a John Craig 70GTQ turbo in full TSM trim and in TSE trim 'little lighter at 3480#s' with some hybrid 72GTQ he went 9.35 @145mph)... Also has one of dem Maximum Effort Race chip thingyma jigs.... Think his name is Roy Garcia and some other guy name Laz

Like Rodney Dangerfield they get no respect but that's okay cause you always have to watch out for the quiet ones

 

[Russ Merritt]

Let us not forget that they did Louies test under controlled conditions and it wasn't a full out race tune-up. (although they did one @ 29# boost and it went to 642rwhp! Shweet!) They were comparing turbos at the same timing, boost and tempature to determine which made the most power. Mine also wasn't and full out effort either as I basically left it as I drive it on the road. Air filter and exhaust hooked up, 21 degrees timing (1 degree less than what they ran), 25# boost (2# more than what they ran). The Turbonetics turbo came pretty close to the GTQ with the limited time I had to try, without some of the things they had, at this power level................

 

[Russ Merritt]

Fuelie! I'm sorry, your lookin for P-trim info!!! Sorry bout that bro.

The only 70 P trim dude I know is Joe D from central mass. Last I saw he ran 10.38 @ 128 with a 70 p-trim .63 HOUSING!!!! That car leaves HARD!

 

[Fuelie600]

I believe Jason Cramer ran 9.90's on a PTE 70mm P-trim. More importantly, are the comparisions between PTE----Limit----and Turbonetics turbo manufactures. I will be running a P-trim for quick spool on the street, but that is not a mandatory factor in these comparisions. Q to Q is fine---Just looking for honest apples to apples comparo's. ( I'm from NY, so I'm partial to apples ). So far, I don't see where the GT/GTQ and Turbonetics show any clear cut gains over one another. Maybe price is the real difference--not so much the performance. Brian

 

[Fuelie600]

I've gone 130 mph on a way loose ( 4500 stall ) Art Carr non lock up with a TE45a P-trim w/ a Precision .63 exh., @ 28psi. Would like to see the same performance with 23-24 psi, and this is why I'm looking at the 70mm. ( and maybe a .85 exh ). Thanks for your inputs. Brian

Looks like those guys are on top. All that power with less cubes. Still running the stock crank at those times?

 

[Fuelie600]

ME-R is a sweet set up. Would any of the above three manufactures be prefered, or do all three build excellent quality turbos? Feel free to PM or E-mail me. Brian

Youve already had good results and good power with PTE turbos (why fix it if it aint broke) Stick with PTE youll make more power and be more reliable. You would die if you knew of all the problems Supra guys have with Turbonetics turbos, they cant get enough of PTE's stuff now.

 

[JCotton]

Thats a pretty impressive response Noclue........ I mean Nojug..... or whatever you go by. I don't know where you get your information from, obviously to me, it is absolutely untrue. I've been selling Turbonetics turbos for a long time, not only to the Gn family but many others as well, they are without a doubt the toughest turbo built. I'm not going to get into what turbos fail the most often, there are enough threads here for anyone to see for themselves, do a search..................

 

[Russ Merritt]

More power and more reliable???? You sound like you've used all of T-netics stuff and had failures and couldn;t make power. Have you?


I haven't, nor have I seen one failure from anything except something coming apart in the motor and going through the turbo on a T-netics unit. Absolutely no thrust issues ever!


I can also remember hearing PTE turbos having problems as I'm sure a lot of other people can too. Makes us ALL human.........


You can say what you wish but I love the Turbonetics stuff, and have had great luck with their products! I haven't used the PTE stuff and I'm sure as hell not going to bash them. Maybe someday I'll try some but for now I'm staying with what works for me..........

Nice pics Russ.

 

[Russ Merritt]

Thank you! Love that Cardomain site. It's easy to post new pics of current projects, new parts. Takes only a minute and helps show people what's out there before they buy it.

Ted, I think we've been thru the stock crank thing before...... Believe whatever you want to believe

Getting back to the topic at hand I think you will find that everybody has their own perference of Turbo manufactures, but if I was you and I had good luck with John Craig (Limit) I'd probably stick with him especially considering his great reputation for customer service Having said that I also don't think you can go wrong dealing with Jack and it is a great sale he's having...

Maybe you should flip a coin

I'm about ready to do that!

I'm going to be speaking with both Jack and John, Monday. I know from experience that John builds top notch turbos, and I'm sure that T-netics does also. I'm truely undecided between the two, and I am confident that Jack sells what he feels is the best product available. Would not hesitate to purchase from either man. That's why I'm still undecided.

Ignore my other post on the same topic. It was presented in the General forum, to gather more response---but was moved here. Sorry for the redundancy. Brian
