I've been told this several times and remained skeptical. Well I've dyno'd with the tst and I'm convinced. Peak numbers show a max gain of 39 hp/ 87 ft/lbs with the tst over just the smarty run. Overall numbers were short of my 500/1000 goal, but everybody was down on power so I'll try again before to long.

What the tst did do was stretch out the power band. The hp gain wasn't a spike, but stretched from around 2100 all the way past 3200. The nice thing is that power doesn't fall off as quickly with the tst, by 3200 it looks like 100 hp difference. Hp does start to creep down after 2800 a bit, but without the tst power falls off quickly after 2500. Comparing the graphs of my three times I've dyno'd, it looks like the cam really helped bring power in a couple hundred rpms sooner, then the tst stretches that power out several hundred rpms later.

Now here's the part that boggled my mind: spring fling 06- 492hp, spring fling 07 493 hp, Claremont 07 493 hp My smarty run was down 39 hp from my previous runs and the tst added 39 hp so no more power when using uncorrected numbers

I was sitting in my truck idling while I'm waiting for my turn to dyno and decided to turn the tst up. When it goes into the competition levels it really gets a big cam type of sound to it, even at idle. So I turn the tst up to nine and within a few seconds I counted five people looking over to see what the heck that sound was Too bad it doesn't fuel as hard as it makes the truck sound

And despite my truck's lackluster performance, I'm told it blew more smoke than all but a couple of the trucks at the event. I think Dave rolled into the throttle too quickly for sw9. I'm planning on trying sw3 next go around.

Anyone know the cure for BB syndrone? K31? 200+ sticks maybe?

David, You have a great running truck, dude. We could meet up sometime and trade housings for a week or so.

Normally the TST makes best HP on level 6 or 7. Also for dynoing try and use an EZ and not the Smarty, the TST/EZ shows better dyno numbers than the TST Smarty stack. As for bigger sticks jumping above a mach 4 showed no gains...... We took a truck running mach 4's, HRVP, Edge Comp, and a Phat Shat 66 and made 605 RWHP, then changed out for Mach 6's and had no gain.

I swear I almost die when I hear this!

I too am on the lookout for someone who wants to swap an SO pump for a HRVP44 and see what kinda difference it makes. My TST is picking up roughly 80hp and about 150tq, and the setting on the TST doesnt matter, it makes the same on 3 as it does on 5, 7, and 9 and there is not much difference in the graphs, just alot more smoke on spool up.

I should add that my highest hp run was with the tst on 2, which Dave recommended trying. Highest torque was on tst 9.

rollinsmoke

when I dynoed my power really didn't change actually my highest HP was on 9

Oh and on an unrelated note, I installed a simflow fuel pressure regulator from Vulcan Performance today. 18 psi at idle and 20-22 at cruise.

These numbers amaze me, alot of truck that i see on the forum running a similar setup minus the HRVP as mentioned are seeing 475-515 hp. Is the HRVP real adding that much more power?

The Smarty is a poor stack for big numbers. Use a timing box like the EZ or Power Puck for maximum performance.

You said it fell off after 3200 - Did you dyno with the competition TST with raised RPM?

Ph4tty

It's a tst comp and it fuels to 3400. I asked the operator to run it to 3500, but my graphs all run out around 3300.

So ya'll think an ez or puck would be all that different from a smarty running sw3 which is just fuel/timing, not the catcher programming?

Mike D

Those numbers amazed me as well. The question should be, is the PS66 adding that much more air? I think someones got a little bit of NO2 on the truck.

CTD2001

I agree with you Mike D, Maybe Doug will chime in here with a little more info about that setup, it just sounds to easy to get that much power.

CarcajouCummins

Yes, the Smarty kills the upper rpm horsepower.

Has anyone proven more horsepower with a hot rod pump on a highly modded vp truck? Any back to back dyno runs? I am considering one, but I doubt it will give me any more power and don't want to waste my money.

Ph4tty

I have heard this, and at this point I'm guessing its the fact that the rate limiter is eliminated in the catcher software so the power comes in too quickly. Good for the street, but the lower rpms the power will hit at means lower hp PErsonal theory only.

Not at the hp levels you're at. The monster vp44's that people are experimenting with now might be worth looking into though.

I dont notice much of a change from my juice off to kill mode, but i know the HRVP has more fuel not sure on the numbers but a so is something like 260cc and a hr is some where like 280cc(not sure on those numbers) but I do know the HR flows a tad more for a fact. My truck pulls alot harder in the top end with the box on but is about the same with the box off at lower speeds. One thing is my truck will not suck air with the HR and it didnt take much to suck air with the so pump.My truck doesnt like dynos 37s through the numbers off or something. I made 593 and 1009 on a dyno jet but only made 31lbs of boost with Hx40 and a so going south. In tulare with a usb and a hr I made 591 and 1290 on a mustang that was reading about 25% low but its just hard to state facts since I changed turbo and it was 2 diffrent dynos....
