Engine/Transmission (1994 - 1998) Bombs With Stock Turbo?

[RT66DOC]

Starting with a '96 5spd 215 pump truck, consider the following power enhancements: #10 plate, 370 injectors, 3K GSK, timing 15. 5, Scotty Air, 4" turbo back exhaust. What happens if the stock turbo is used with these mods?

Nuclear hot EGT. With the same truck/starting point as you, I ran a #11 plate with 300 injectors & was @ 1500 degrees.

 

[DBogo]

how would those mods be on a 175 pump

370s

11 plate

BHAF

straight 4"

HOT!!!!! I have a 215, 100 plate, scotty II/UNI, and good 3" and it gets HOTTTT!!

Tom you will be way to hot.

West of Larmie I would guess you are around 6-7000 feet which will make it even worse!! I am at 7,000 or so and I just slide my plate all the way forward last weekend and it gets hot real quick and I don't even have injectors.



You will also need a good clutch to hold that power at least a OFE.

Don't do the injectors unless you are going to do the turbo. With that setup I would say you couldn't stay in it more than 4-5 seconds without 1500 plus!!! No joke



Dbogo go with the #10 slide it forward until you find a happy medium with egts and power. Get injectors when you plan on doing the turbo because you will also be way hot even at sea level.

i ran my stock turbo with 370 #10 plate full foward afe intake and 4" exhaust to 5" stacks and could only get to 1500* if i realy tried and i was running 45 psi not smart but i did it and stock clutch didnt stand a chance

This is probably gonna be about the same as asking what's the best oil but I have to do it. :-laf



Next logical question: OK, so which turbo for low end quick spool up with these mods?

 

[pwerwagn]

I think if you wanna do a #10, 370's and the GSK, you will be happy with a B1. A mod'd HX40 might suffice (something like the DD jammer) also. Depends on what you wanna spend. The HTBG-HTB2 line is nice because you can try the BG and upgrade to the B2 or the Killer B or SP66 if you want to for not much extra cost.

If DD ever gets the BB jammer worked out, that would be sweet for that combo also.

oh yeah, and your stock clutch wont hold the #10, let alone 370's.

 

[RT66DOC]

That's where this all started---> need new clutch, so... Y'all know how it goes.

I have a 1994 160 pump converted to 5 speed

with 370 injectors 191 dv custom plate simaler to the 10 plate

37# boost stock turbo max egt 1375 WOT

Howdy NWitmer. 1st post - Welcome.

Thanks for the info.

BTW, I've been to Lancaster.

Doc, I would probably skip even a modded HX-40 in you case. I'm seeing 1200* with my setup, and won't have the 191DVs in 'til Saturday.





NWitmer,

Welcome to the TDR.



FYI, your 160 pump isn't pushing near the fuel as the 215 would be.

 

[RT66DOC]

So maybe HTBG=HTB2?

Just got htb2 yester day . Of course it was in in no time . Smashing and bending the return line was a major cock . I would highly suggest a bolt on should be marketed Well at any rate i was running the stock turbo with the 16 non gated exh. and a 60cm compressor this worked ok but lagged at low rpms . I had put a tighter afc spring in to help cut smoke . But now i think i will go back to the light one and slide the plate another 20k . I have the baby pump so i would have to say skip the hybrid and go right to the big boy plus it can be used for the top turbo for twins . No money lost this way . HTB2 less smoke yes, less egt yes , power need more fuel first. MIKE

I was told by a Cummins mechanic that at 1200 and things are glowing red. 1220 is the melting point of aluminum which is what our pistons are right forged aluminum. Has anybody melted pistons my egt get to 1300 and I get nervous. Or am I misinformed.

Ran a 100 or whatever you want to call it plate with 370's, stock turbo 16 housing, 15. 4* timing and did well with it at around 700 feet elevation in San Antonio, moved to El Paso at around 3200 feet and it was almost worthless, pulling mountains empty up to around 6000 feet and it was worthless, had to down shift to go 55mph and keep the temps under 1200*. Got a HT2B and things are good. I believe melting point is in the neighborhood of 1350*, though read of racers hitting more than 1600* (non-sustained) and have been fine. Maybe somebody can chime in to add more info on the topic. Once read here that pyro readings of exhaust are usually higher than actual metal temps inside the engine, so short periods of time at a temperature reading above 1200-1300* are okay but sustained can lead to aluminum melting and mechanical failure. Am I on the right track here fellas???

if you installed it right you wouldnt have to bend and smash the return line i have the sled puller 66 and all i had to do was losen the exhaust and compresser housings and twist it around then it fit just fine we also did one on cahammers rig and did the same thing works great if you know how to install it :-laf

 

[Neibe]

I just search melting point of aluminum on the internet and the answer is 1220.

It depends on who sets it up. I set a truck up that was much like this and it would make 1800+, went to a 18. 5 housing and Water/Meth and brought it down to 1550 area... ... 446 on #2 and 496 with 50/50 mix.
