Engine/Transmission (1998.5 - 2002) tst pm3 stacked?

[hemijustin]

TST Comp, EZ, AFE stage 2, 5" into dual 4" PDP exhaust, southbend 3600lb 12 cb dual disk clutch, -8an fuel lines with wildcat fittings.



No 1/4 times or dyno numbers, yet. Truck needs a VP before anything else right now.

how do you like you dual disk? how bad are they for street driving?

 

[LOtero]

how bout those egts with stock turbo, tst ez and injectors?

Love it.



There is a little more pedal pressure, but it is not an issue. Only thing you will really notice is increased noise from the center plate when the clutch pedal is pushed down.



Plus, the trans can be slipped a lot easier then a single disk with the same holding power. Makes backing up to a trailer, launching under boost, or starting to drag a sled a lot easier.

i think im ganna save up and not mess around. iv only seen the south bend dual discs does anyother company make them. what kind of price are they?

Justin

 

[JGheen]

I believe Enterprise Engines makes dual disks as well. Ask Craig Johnson, I think his is an Enterprise Dual Disk. I would probably stick with a SOuth Bend as Peter's customer service over there is probably the best around.

Your probably looking at about $1500-$2000 for a DD. Check the websites, they have pricing.

thanks joe...



i just read that the mad ecm and catcher compleatly replace the ecm. is this true? if so i wouldent have to pay extra to get Dr. p out of the system.

 

[hemijustin]

ok i just started thinking about this... if the EZ give me low boost fuel then i wire it in it goes befor the tst tricking it into fueling sooner as well. is this what happens? never really thought about it before

EZ does not directly give any fueling. It modifies timing only. Advancing the timing will cause the computer to add a little fuel, but will not alter the way the TST fuels, as the TST is based only on MAP sensor(boost).

Justin & Lotero,

Yes, I'm still running the stock turbo even though I shouldn't. My max boost is usually around 42 but I've seen 45. My egt's aren't as bad as I thought they'd be. I can get the temps up fast if I'm climbing a grade, even empty. If I'm towing anything heavy I usually turn the pm3 off or dial it down to 3 or under. I've seen egts to 1400 for a few seconds while on grades and usually no more than 1200-1300 under hard acceleration. The install could not be any simpler, just plug it in. It did help alot with low boost acceleration. I'm off the line quicker, then the TST kicks in and it pulls like a freight train.

thats exactly what i wanted to know aaron, thanks! i am now very convinced to buy an ez to stack. if i remember correctly both the ez and the tst plug into the map sensor, am i right or is there just a splitter or something i need to buy?

 

[Double A]

You don't need to buy anything. Just read the directions and get to it. If I remember correctly, the tst plugs in first, then the ez. I'll check it out in the morning and if it's any different I'll let you know.

with what im runing i see 35lbs of boost and can hit 1400 in like for or 5 seconds in 6th. but you have and intake system and 4" all the way out were i have straight pipe soon to change... htb2 got a 4" downpipe. . will that really make that big of a diferince?



i raced a ford on my way home from work... . he beat me off the line. . i hit 4th and started gain, missed fith and fell back but cought up quick and sat next to him thinking he was done but noticed he was still given er hell so i put the throttle down and pulled away from him befor getting cut off... . he did have an auto i didnt realize he wanted to race me... i need more take off. and maybe some lessons in hitting 5th gear... and lanching with out my clutch slipping

Justin

 

[Double A]

All trucks are different, but the scotty 2 and the exhaust did help me. I had the TST on the truck before installing the exhaust and the intake and I never saw 1400. I used to have mach 1. 5 injectors and moved up to 2. 5 and that is when I really had to watch the egt's. I don't think the EZ really did much to increase egt's, so you should be o. k. if you watch your gauge. As far as drag racing, it's not easy with a stick. You need a clutch in a bad way. I launch in 3rd in 4wd, shift out of 4wd, then into 4th and so on. As you can imagine, you can't really do that at a stoplight with out creating a scene. I really only do that on the track, or if a Ford is sitting next to me.

i gess i do need a clutch i take off in second i tryed 3rd once. in the rain but the clutch didnt hold... thought i do a wicked burn out but nope. im saving for a dual disc! then ill have a rematch with mr new ford... ... :-laf

 

[Double A]

Some guys I know with 6 speeds launch in 4th. You can launch in 3rd with a stock clutch but you have to get it just right. If you rev too high, you smoke the clutch. Too low and it stumbles, but when you get it just right, you'll smoke the tires. You do have to slip it a little before it hooks up.

BTW: If you want your stock clutch to last awhile, don't try it often.

 

[JJ Jackson]

Double A, what is the difference powerwise between the TST/EZ stack and the Comp Box? And if there is a noticeable difference can I stack the my Comp and the TST, if I pull the pump wire in exchange for the TST pump wire? Thanks... ... Jim

 

[Double A]

JJ,

From what I understand the TST only adds fuel, it does not alter the timing like the edge products. By stacking the TST with an ez, you get both fueling and some timing alterations. The edge comp already does both of those things and does it well. Also, the comp does not defuel at the stock rpm levels. There are others on this site that can answer this question better than myself so hopefully they will chime in. I think that if you tried to stack a tst and an edge comp, bad things would happen :-laf

Aaron

 

[JJ Jackson]

Thanks Aaron, so you say the Comp works well on its own so I guess the stack thing isn't worth it. Hey, you ever broke anything dumping the clutch like that? I've always wanted to try it, but been afraid of dropping some much needed parts out from under the truck... . Jim

 

[Double A]

Haven't busted anything yet, but you always run that risk. I don't just rev it up and dump the clutch. I slip it a little untill it hooks up and then take off. It's not easy but it works best for me.

Aaron

 

[LOtero]

ahh the joys of having an auto... :-laf
