T76

[smokinrod]

Is anyone running a T76 as a single charger?

 

[Cooker]

I'm guessing it would not perform well, in reagards to drivability, as a single.

 

[smokinrod]

what do you think if you were sled pullin with a very loose converter truck?

a Y2K T-78 or T-80 would b alot better than the plain T or u can get the super T in a 76 but still not better

even with a P or Q trum wheel, it on't be much fun... . it will either be laggy of surge like crazy.

 

[smokinrod]

what I have is a GT42R ballbearing which people tell me is the same as a T76

turbonetics ,all I wantr is to know if it would work on a street class puller with a very loose converter.



Specs that I know:



94mm inducer

meets 2. 8 rule

1. 15 exhaust housing

If it's equaly to a GT42R, then it won't be too bad at all. For sled pulling and a 2,200 stall converter it will work like a Champ!



With a Comp, Mach 4. 6's and a 42R, friend of mine put down over 550 (IIRC 580) RWHP, and ~8xx rwtq.



Driveability was descent, but not wonderfull. I wouldn't be afraid to put it on a street/strip truck (more strip than street).

There are two versions of the GT42



Only one meets the 2. 8 rule. It is the GT4294R the 94 is the exducer not the inducer. It is actually smaller than a T76. The T76 does not meet the 2. 8 rule. Obviously... it has a 76mm inducer



Air flow for the GT4294R is 85 pounds per minute or, 1130 CFM



Air flow for the T76 is 91 pounds per minute or 1210 CFM

This is why I love the Cummins guys , you all are so smart. Thanks very much ,



One last thing so according to that turbo chart floating around here a HX55 would also be about the same as a GT4294R (as in flow #'s). so it is just a little bigger than my JR lil55 ? Sorry for being so turbo stupid.

Good Question. According to Holset the HX55 is good for . 75 kg/s or 99 pounds per minute or 1316 CFM.



I kinda doubt with flow numbers like this it will meet the 2. 8 rule.

Holset HX55... 67/77
