With mach2.2edm,s tst powermax 3 (comp) and a B1-2 turbo making 52 pounds of boost i can hit 1500 anytime with the box on 2 or higher. What can i do different.

 

About the only thing you haven't done is the Scotty II.

Cooler air in = cooler air out.

BHAF is hundreds times better than the stock airbox/filter, but it still pulls in hot underhood air.


There's always less go pedal.

What i would like to know is are all high hp trucks say over 400 hp cruising at half trottle whatching the pyro? Or will twins do better to keep you cool.

 

I see 650-675°F cruising @ 80mph, 2600rpm, 5th gear. Peak is 1320 with outside temps at 95°F. This is with pdr40/b2 twins, mach6's, dd cam & tst pm3 comp set on 'kill'.

I think the answer to both questions is yes. Twins will run cooler with your set up - but beware of head gasket problems - your close to the limit now. And many guys have to monitor EGT's as the limiting factor - I do.

Been looking at the B1-2 myself. Can you control smoke with light pedal when you want to? How's the spool up?

RJ

 

Spool up is very good and smoke with light pedal is very faint but look out with heavy pedal till you make boost.

 

This is surprising - From what I have read here I thought the B1 would keep the EDM 2.2s a little cooler.

Is the B1-2 the quickspool model?

What size of exhaust housing is it comparable to? (ie 14cm, 16cm, 18cm or ?)

Do you have a wastegate?

TIA

Think you'll find More Powers' problem is his TST Comp Box, not his injectors. That box pumps more fuel than any box on the market, IMHO. His box puts on as much fuel on #5 as yours & mine does on #9 setting.

His B1-2 is not the KwikSpool model, That would be the KSB1-2, which I have. The B1-2 has a bigger housing with the same turbine wheel as mine, and is good for about 50-75 more HP. Holsett is only Mfg. that uses cubic cm dimensions so not sure, but would guess B1-2 is between 16-18.

If interested in full rundown on B-1 options go here for ROD's comments;

G.A. Do you run out of EGT on #9, empty, with your set up?

RJ

 

RJ

I can run out of EGTs on #9 unloaded getting on the freeway if the on ramp is up hill in 6th but I don't like going that fast in a truck. In the lower gears the tach climbs faster than the egts and I run out of rpms.

Thanks for the referral back to the other thread.

FWIW my wastegate opens around 40psi of boost - which is enough!


George

 

George My exhaust housing is arouond a 16cm and my turbo is a wastegated turbo not to many B-1s come that way but thats how i wanted mine at the great price of 1800 dollars.

 

It is my opinion that you need more timing advance. Try stacking an Edge EZ with your setup. The TST box does nothing with the timing. You are making great boost, and burning lots of fuel. You need to start the burn sooner. I dont have the Mach 2.2's like you do, but I do have RV 275's and the TST box. With the stock HX35w I could hit 1,400 and would allways seemed to run 1,350 when I was having fun. I stacked the edge with it, and I now can NOT MAKE it hit 1,300 no matter what I do, literally. FLoored, 6th gear up grade the whole time up to the rev limiter at about 105 MPH, 1,200 to 1,250 tops.
It is my opinion that is part of the reason the 12V guys are running tons more fuel than us and still keeping EGT's sane, they have control over their timing, and know where to put it.
PS, I know its a gasser, but on my drag car I can make the headers glow red at IDLE by retarding the timing..... Think about it a little bit and you will understand why........The same principles apply to a diesel.

Zino

 

Zino is exactly right, as usual

When you're burning so much fuel, it takes time. There's a good chance that the fuel is still burning when the exhaust valve opens-- thus the high EGT.

Your engine will be more efficient if you can get the EGT down. More timing lead is probably the right move in your case.

Here's the other thing so consider-- try turning your box up to higher levels. WHAT? Yes, higher power levels.

The B1 is weird that way-- it likes to work. There are many reports of people seeing LOWER egt after cranking the box up a few levels. Try level 4 or 5 on that wicked TST comp box.

Have seen this personally. Only explaination I can come up with is higher setting (more fuel early) brings in more air early and makes egt's climb slower?? Higher setting will result in higher egt's if you stay on the throttle, but does seem to take longer to get to extreme temps.
Worth searching around for the best balance for your setup...may just be a higher setting.

Let us know, huh?
