Give me your opinion of the two turbo chargers..
Turbonetics GTK 1000 or Garrett GT4202R
gtk 1000 = 76mm comp wheel
gt4202R = 74.7mm comp wheel
both rated at 1000 horsepower
Will be used in twins, on sbc 358 cubes
drag race only.

page 17 of the garrett turbo chargers 2008 cataloge says...

"a clear demonstration of the inherent superority of the garrett ball bearing design is in the LAUNCH of a turbocharged drag race car. The TWO STEP rev limiters used to build boost on the line expose the turbo to the harshest imaginable conditions of the pressure spikes and scorching temperatures. Where lessor turbo's often fail catastrophically, garrett ball bearing turbo's regularly shrug off these brutal conditions time after time"

I could not find anywhere, turbonetics saying 2 step rev limiters would not hurt there turbo's...
BUT
Turbonetics give 12 months unlimited warrenty on there turbo's

which turbo's are better??

I came from the import world where we use 2 step and anti-lag on every launch, personally I always used the garrett turbos and never, ever had a problem with one

im personally diggin all the new borg warner stuff. same performance at a fraction of the cost! imma start carrying their line soon after i tried their S372 on my supra compared to a GT42R. bigger and makes identical spool time for 700$ less

Right the bw stuff is awesome and the modded bw stuff is really starting to shine.

I'm running a gt4508r ball bearing and love it....I believe you get what you pay for, so alittle more cash now and less later....good luck with your build...

crashly

so other than the $$$$$...
the turbonetics stuff is ok ???

I had a problem with the gtk 550's , turbonetics could not do enough to help me.... they just bent over backwards to fix the problem.
Great people to deal with.

Have twin gtk 1000's on my 358 sbc..
Just checking that i bought the right ones, VS garrett GT's

TC76's would have done the same thing as the GTK's. A little cheaper as well, and still great turbonetics warranty.

thanks for replies.

looking @ your web site...
http://www.forcedinductions.com/productturbonetics.htm
the tc series t76 advertise @ 1000 hp
the t series t76 advertise 1100 hp.... more than the gtk's ????
the super t 76 advertise 1200 hp....

i thought the gtk 1000, ( 76mm comp wheel), with all its super surge ported comp housing would have been better??? , but it's rated at 1000 hp

http://www.forcedinductions.com/productturbonetics.htm

are these gtk's under rated??? because they are new??

there is a turbonetics video, with a supera , they pulled a gtk 76mm off, and fitted a super t 76.... went 956 rwhp @ 35 psi

http://www.turboneticsownersclub.com...908&highlight=

is there a major difference from the gtk's to super T's
both have surge ported comp housings, SAME comp wheel

cheers

i have heard of some of the Evo guys, well one, having problems with his BW turbos. blew 3 on his race car after only a few dyno pulls. he was pushing over 50lbs of boost though.

by the way these were not modded turbos but just normal BW stuff.

thanks Chris.

cool ideas/ info

Those were Bullseye Borg warner turbos. 3 of them blew up back to back to back . They couldn't fix the problem so he called us.....USP is now running just fine after he told us what was happening.

We can build the TC's the same as the GTK's now without the pretty ported cover though....but you don't need a surge housing on a big v8, plus surge housings decrease power by a few % anyhow.


We can build the Super T's as well now.....but we can do them NON-BB where you can only buy them BB direct from T-netics. That will be offered after the new year. Also their is more to a super T then just the pretty belled cover.

I have a pair of GTK-550's sitting here...

The drilled housing on that unit is purely Cosmetic. the drillings are dead ends. Still looks good though

Not sure how many actually have functional drillings.

Im running 2 of these on my built 408/ET 240cc setup. Should be done in Feb! I will let you know how she does!

hmmmm whats the benefit for having the TC upgraded to the GTK specs and price for an upgrade for those of us that have one.

Tell us more about your Super T

DrTurbo

iTrader: (3)

If you already have the TC unit with MPS, not sure it would be worth an upgrade to the F-1 turbine wheel. Now we can build the TC's with 3" DP's and now 4" DP's as well.


As for the Super T's shoot us a PM. We can do them with BB, non BB, water cooled, , bell inlets, billet comp wheel in some apps....etc..etc. Endless amount of different configs.
