Mid-Tenn Chapter Roundtable

[Bling-N-Smoke]

That's some Piston Slapper paws too on that flex plate!



Funny story, I was in Waverly yesterday. Guy comes up beside me in a dodge dually. Rolls down his window and says "Are you piston slapper?" I said "yeah". He said "you worked on my truck, thanks!" Gives me a thumbs up and smokes away pulling a trailer with cheerokee in tow. I was floored, cause I didn't even know the guy... . I later found out I did know him. Funny story anyway. Waverly knows the Slapper!

The Piston Slapper is spreading like a bad plague!

 

[Kimber]

Get ready.

People from across the land will be spending thier last dimes just to get The Piston Slapper to "lay hands" on thier trucks. :-laf

[BigPapa]

GShultz, how'd it go with Meachum? Hope ya'll figured something out.



Hans, I found you a bench seat out of a Chevy Luv. A friend of mine has a junker he bought for parts and he said he'd sell the seat for $50. It does need covering. He also built a little step side bed for his. Looks kind of like one of the early '80's Chevy beds.



Mark, I never heard anything back from you on the CB mount. Give me a shout.



Andy, I'm going to order me a vacuum pump seal kit from fixinrams.com. If you want one maybe we can get a deal on two.

Scott - excellent! PM sent.

Showing my true 12v noooob-ness here...



Does anyone KNOW if this is "excessive" blow-by or not?



The nickel is for perspective, and the links at the bottom are for higher res-images.

Mine makes a mess after a few days parked. I like to keep some cardboard under it if I'm parking indoors. Mine leaks out the front and the back and the blow-by and some other places. Keeps the pan from rusting.

 

[HeavyHauler]

Hey guys - I've finally talked my buddy Darrin into going with a 12V for his Ford Crew Cab. He just called and said he can get a running 12V out of a '94 for $500. We're going to go look it over later this week.



Any opinions on this? I know it won't have the 913 pump, but surely we can get it to run good enough to pull his enclosed trailer. Or we could always swap the pump.



I notice those pumps sure don't respond as well to cam plates and such. Is there any reason to stay away from the '94?



He's got a 24V block, head, crank, cam, rods, and all that he's going to try to sell any way he can. It was in a fire, so I'm not sure what it's worth. I'm going to take some pictures Thursday and post them on here to get some opinions on value.

 

[Cumminsman]

fix the dowel pin in the front. it will most likely have a 160hp pump. you can easily get 400+hp out of that pump.

 

[HeavyHauler]

Yeah, I figured we would have to do the KDP fix. Still not sure what pump it has (don't know if it's a manual or auto). Yeah, after I got to looking at it - a mild cam plate, injectors, and maybe delivery valves depending on what injectors we use should be able to make some decent power. I just hope the right turbo can keep it all cool while towing. That's the main goal.

 

[Got Smoke?]

Hans I can get you a copy/template of a #10 plate to do a home ground job that would be the most cost preserving for HP way to go.



Scott... ... I'm still up in the air about doing my radio that way. I didn't consider the fact that I run a set of re-tuned radio shack meter's in my truck 24/7 so where am I going to mount them? Not to mention the problems I'm going to have with the gauge pillar..... wrong model pillar. . its glued in place up top... . thanks previous owner.



Also I want to do my air valve whenever I have to fool with that dang pillar... . for now it will have to wait... . maybe later on this summer we can make a day out of it... . do the radio and valve in one day.



Oh yeah boss made new March schedule today... ... ALL SYSTEM'S GO FOR BDP Dyno Day! Oo. Oo. Oo.

Anything 370 size or bigger will require bigger DV's to get ride of stumble/stutter the small pumps suffer from.

Mark, do you think a #10 is too aggressive for heavy towing? I was thinking a #11 might be the way to go but I'm new to all this. He'll be toting somewhere between 15,000 - 20,000 pounds (maybe more) with that trailer loaded.



Also, are 370s a little silly for towing like that? Would we be better off going with something smaller?



He just became a TST dealer with my encouragement so he can get a cam plate for less than $100 I think. We'll be talking more about this though!

The #10 plate is the most well rounded fuel plate. Brings the fuel in steadily, and then on the top end starts to defuel some. I'd say with the #10 alone he would have problems towing that heavy with a stock clutch. Surely while doing the swap he will upgrade to a performance aftermarket clutch.



The #11 will have less fuel, but why spend $100 when you can take your stock plate... . easily grind it to a #10 style and if its too much fuel just keep sliding it back until you get it to its desired level.



If he's going to be towing that heavy a plate alone is going to do a # on the stock turbo, I wouldn't worry about injectors unless he's planning on doing a aftermarket turbo right off the bat.



The best injectors for the $$ in my opinion are Pier's 370's. I had a set of marine 300's and swapped to Piers 370's. Even though they were bigger injectors they burned better (read slightly lower EGT), and produced less smoke than my 300's. That's because Piers matches each set to similar pop-off pressures, so each set is a matched set of injectors. For $400 and the ability to support up to 600-700HP (I know he's not going that far, but its been proven) they are hard to beat.

 

[HeavyHauler]

Yeah, we're gonna do this deal right. He may or may not need a clutch upgrade immediately, depending on how he drives it, but we'll see. He'll do it if he has to. Since he's going to end up getting that motor so cheap, that freed up some extra cash for goodies. I've already told him we're gonna have to do a turbo upgrade, so that's in the works.



So assuming it has a 175 pump, do you think your basic HX40 would keep 370s, DVs, and a #10 plate cool? And maybe throw a slight timing advance in there too. I'm thinking that's only going to put him around 300 RWHP. What do you think?



In 24V land, that's not even stressing the stock turbo, but I'm guessing that the 12V is a little different being that the power comes in so much earlier, right?



Good idea on the #10 plate though. I've got to remember we don't have to go balls to the wall on that thing. Backing it off a little should work.



So is it really that big of a deal to have the pop-pressures all matched on the 370s? I know TST carries them too, and he could get a lot better deal through them. I'm not sure if they match them or not. Any idea?

 

[WadePatton]

Throw the little pump over a cliff. Get a 215. call me for the secret source.



IF that isn't done, then believe me now that the best thing I did for surge/stumble/chuggalug when I was running a little pump with 370's, #4, and 180dv's--was TRACTION BARS. No poop.



I've got a #11 I'll swap for a #10.



AND I find 12-valvers need a little more turbo. And a 3-piece manifold should help more--but I haven't gotten that far.



Cheryl gave me hell last night on the hill, her in the Red one and me in the Green one. But then it's fun racing your own truck--win/win! :-laf

andy, whats up, how did the install go? don't keep me waiting.

ya skirt :-laf

 

[AndyMan]

It went painfully slow as you might have expected.



Runs out good though. Strong. Nifty set-up.



For everyone else: We installed a beta 24valve Juice/Attitude on Fegers truck last night.

For real, we made over 500hp with a 160hp pump on Ole Smokey. You can make them squirt. Piers builds his stupid pumps from 160 pumps. 660cc/1000.

 

[WadePatton]

I'd let it bounce one time before I grabbed it.



Maybe I should preface that with--IF you can find a junkyard 215 for less than $1000, THEN I'd chuck the little pump--unless I had a VP that needed replacement. :-laf



Daily driveability and smooth power throughout the band are what make the 215 vastly superior.
