Engine/Transmission (1998.5 - 2002) high egts and want some opinions please

[RolandJ]

so your saying if i went with twins i need a diff turbo for the smaller one than i have now . i mite as well get the tool cart out and take the injectors out

 

[Forrest Nearing]

well, the twins will cool better than your current single, they'll just spool up a little slower. how much boost are you running now?

 

[RolandJ]

roughly round 39 i think

 

[RolandJ]

well i took the injectors out tonite #@$%!... so im back to stage 1 of picking an injector that will work w/ my turbo and for towing ... .

 

[DCreed]

stay around a hundred horse injector w/that turbo

 

[RolandJ]

i wish i knew that prior :{ i guess maybe ill go with 1. 6s is that good for towing too?

 

[BILLVO]

Get rid of that turbo and go with an sp62 or sps62 and put the mach 4's back in. What kind of performance are you looking at. Is towing or performance more important to you. You stated cruising egts don't matter. I think with your 6speed a silver 62 would be awesome with what you have. The silver is a bit to much for my 3. 54 and auto it takes a lot of rpms and fuel to make it happy.

well i have a boat trailer the i move alot in the summer and trailers pretty often on weekends and during the week so i need it to be drivable . . so i guess id say towing but of course i like performance too :-laf

 

[BILLVO]

I would go with a 40-60 hp injector if you stay with that turbo. No larger than this on injectors or the egts will still get high while towing but ok while just driving.

 

[Forrest Nearing]

seems like you should have gotten more boost out of it than 39

 

[RolandJ]

i prob can but i have to let off cuz the egts are too high ... ... my head is spinning from this lol i dunno what to use any more...

I only got 42lbs out of my Bd superB with M-4's, a HRVP, and a Blue Chip FMS. I could peg the EGT's gauge within seconds. I suppose that's why my old head had 40 cracks around the valve seats

 

[RolandJ]

warpig, im glad im not the only one i think i may buy a new turbo :-laf maybe an industrial injection phat shaft 62

 

[Cummins724]

Which super B do you have? The older B's had a 59 wheel on the exhaust side & would spool really fast, but not cool. The new Super B's have a 65 wheel... S300. They are pretty much the same as a PS62. With M4's you should see your boost gauge peg out. I think that you may have a boost leak somewhere if you are only getting 39psi..... possibly need to adjust your wastegate.

i have the bd super b single . . the egts climb fast all the way thru. . there gotta be sumone one out there who has an answer

Boost gauge peg out?? I don't get over 52lbs with a Silver Bullet, M-4's, FMS, SMARTY, and a HRVP with a plugged wastegate.

Don't confuse the super B with the Super B special which is comparable to a sp64 I believe. You can get the sp62 with 12 or 14 cm exh housings I think the BD,s are only 12. My super B I had about a year and a half ago Had the same egt problems he is talking about and I had 90 hp sticks. I would only get around 38-40 psi tops also but could peg my 1600 egt gauge in seconds at wot.



IMO he can keep his current turbo and go with a lot smaller injector like a Mach 1. 6 as he just wants to control egts while towing from what I understand from previous posts.
