XLR8R, I might try that someday. I've heard both sides of the discussion for going pre CAC or airhorn. For ease of installation I decided to try it there first. I thought the gain was pretty good, I was expecting less.

I would like to see some results/dyno graph showing hp at both locations. I've been looking around but haven't found any yet.

Floorman:

Yeah, your right, Phil's truck does run good right now. But,.....did he tell you that it is running that way because he has my old "Scheid Built 180 Pump" on there now and not his old "stock" 180 pump??? I will say this though,.........a race between Phil's 98' 12 valve on #2 and Mike D. with his 24 valve on #2 and NOS would be pretty interesting. But right now Phil isn't gonna be doing any racing until he gets that bad oil leak fixed on the front of his engine.

No reason to sweat it on a diesel but on a gas vehicle if you leave the line without your n2o line purged your car is gonna fall on its face off the line from all that fuel and a edited by admin n2o hit.

His truck is darn fast. That Scheid pump puts the fuel to it. He might be too fast for me now.

Although, I ran a 12.87 with a smaller jet than I used on the dyno, I'll take your advice Mike and put a bigger one in there just in case.

Since we are on the nitrous stuff. Heres mine (I know it's not on a cummins but a cummins pulls it around). And yes it was very costly $$$$$$.

EDIT: Forgot to mention that typically the more expensive kits add a progressive controller and bigger feed lines to help you down the nitrous junkie line. I don't think it's a bad thing to start out with a $300 kit, but that's all you'll end up with if you want to go bigger later. JMHO of course.

brandon.
Local diesel shop did a similar set-up for a diesel powered boat. The pumps fueled way too much at low boost levels and turbos wouldn't spool up. A manual nitrous switch controls smoke until the engines and turbos spool up.

Mike, Now that you've got your transmission done and a bigger turbo, you should bring your rig to the track and we'll line 'em up. What's the fun of having all this stuff if you don't race it, right. I'll promise to leave the nitrous off. What do you say?

My truck is slow without the nitrous, it should be a good race...

Floorman:

"For the record",......you are right, Phil and I did do some "horse trading" on parts and that stock tranny you say was "your stock one" was part of that deal. However,......so all the facts are straight here,...Phil also got my 2002 47RE case along with all the high energy clutch packs and "modified parts" that were inside that transmission, along with us working a deal on that HIGHLY modified Scheid 180 Pump that was in my 1996!

I also find it pretty funny (although you did say you were "busting Mike D.'s chops) that you are on here giving Mike D. a hard time with a truck that is not even yours!!! As he said, bring that truck of yours out to the drag strip sometime and lets see how you can do against Mike D.s truck, #2 diesel only!! My guess is,......you will LOSE!!! We will let you know the next time we go to the drag strip!

Kerry (abc4yew) did just that on his truck and consistently found the most benefit from injecting the nitrous pre-CAC... I believe a large factor in this is the NO2's latent heat of evaporation cooling the combustion chamber/piston crown too much for best power (and BSFC)...

but we know that it'll help wherever you blow it in there!

Do you have any more details, XLR8R? Was it just a single shot and to what percentage was the gain?

This info is from last year - have you tried a search?

I'm sure Kerry would be happy to give you his findings!

Sounds good, Mike. Hopefully, we'll be able to all meet up sometime soon. If you get that Quad box you'll have a even better running truck. I've lined up with both of John's trucks and lost, but I've always had a good time. That's what it's all about.
