Tell me this would not be the most aggressive, hard core, put your foot down and get fuel NOW, 4,000 RPM screaming setup, short of a P pump conversion. :

I have heard, read and know plenty about the MAD ECM... Who all owns, or has driven a Blue Chip Redline box?

Whadya think?

From what I've read, to rev that high on a 24v would require some new valvetrain as the fatory stuff is to heavy and you would get valve float. Other than that, combine those two with a set of mach 7's, a good size twin turbo setup, ported head and cam, a fully built tranny, and a hot rod vp44 and you'd have one mean truck on your hand.

 

Yup, youve nailed it. Thats exactly what I want to do, but I was think Mach 5's maybe 6's max, so I could get reasonable turn down.


Kevin

 

Wuss. Put those 7's in and have fun.

 

shoot a pm to OL BLUE, he had great results with the catcher ecm and TST box

 

I have heard that the Redbox is pretty hard on VP pumps. The valve train mods are pretty pricey. I looked into and if I remember correctly it was about an extra $1500 cdn . Piers told me that that Red box and the valve trains mods would add 10rwhp and a race VP is about 20rwhp. Kinda expensive horsepower. A bottle or methonal is cheaper bang for the buck. Unless someone builds a better VP pump why bother with a race VP pump. There pretty pricey for something that only last a year or two.

Has anyone tried mach 7.0 with a all out race P pump on a 24V truck? I think that one is the hotter ticket.

 

Numbers are misleading, are we talking peak horsepower or horsepower curve? For instance the Redline box will more then quadruple your horsepower at 3700 rpm.............of course nearly all boxes except the Redline are defueled to stock horsepower by ~3200rpm. At 3700rpm the Redline box horsepower may not look that impressive on a dyno sheet due to poor airflow, but the Redline is still fully fueling the engine so if you can get the air through it at high rpm............. If you want a dyno queen then tune for max horsepower ~2800rpm and maybe no Redline is needed. If you want street, strip, or sledpull extended performance then it may be advantageous to set the Redline to 3500rpm (or whatever) so that the truck will not defuel early. Some stock ECMs start to defuel ~2700 and like I said most are way into defueling above 3000rpm, huge injectors can compensate a bit, but defueling still happens. Anyone that has had a early P-pump 12 valve truck knows that either a 3000 or 4000 rpm kit will make the truck much more driveable just by EXTENDING the rpm range== no additional PEAK horsepower required. The Redline does the same thing as a governor spring kit except that it the rpm is adjustable with a button inside the cab and it also (can) wrings more fuel out of the VP44 if you use the higher setting and higher level then say a Blue Chip FMS or Comp box.

My take on the RL being hard on VP44's is that most anything you do to enhance the fueling of the VP is , but short durations of high settings are very doable. If you don't want to pay ($'s) stick with injectors only and good low pressure fuel delivery but heck, what fun is that?

Mach 7's with a 13mm bbl. P7100 race pump would require a lot of air, check into tandem turbos and good porting. Single turbo I'll bet on the VP44 with Mach 7's for a better across the rpm band power. Larry

 

I'm still trying to locate these Redline dyno sheets. I've asked multiple sources and cannot seem to locate these mythical creatures. Who's got 'em? Thanks!

brandon.

 

I have about 50 or so now with Mach injectors. The redline rocks!

I will work on getting some posted in the next few days. Power is good at 4000 rpm, all things considered.

What boxes can u stack with redline?

 

Yes Roger, I could not agree more. It is painful to launch a 6,700 # truck properly in second gear, only to have to shift within nanseconds into third, and then a split second later into forth, cuz the damm engine de-fuels at 2,700 RPM. 4,000 RPM shifts would make a street truck literally seconds faster in the 1/4Mile and TONS more fun to drive...

As for horsepower, this is also one of those undenyable facts of physics...... HP = (Torque * RPM)/5252.
RPM makes horsepower, plain and simple.. As long as torque does not drop off faster than the rate of RPM increases, you are making more HP at the higher RPMs period.. I dont spin the small block Chevy in my drag car to 8,800 RPM cuz I enjoy changing valve springs and rods every year......


I would be willing to guess that even a stock HX35W turboed truck would make SCADS more HP fully fueled at 4,000 RPM then the same truck at 2,700... Not to mention TONS faster in the 1/4m...

Don M, what have you found out with the Red box? Have you tired it on your mach 7.0? I've heard that your injector pressure drops to far off on a stock vp pump.

I was going on third hand info cause I was throwing around the idea of using that box. I've heard that the red box is the thing to do for drag dracing as you can extend your shifts. If the power and torque is the same thru out the rpm why spin the motor so high, for the rest of us. I've been looking into a P-pump conversion, but it kinda just moves the truck from a fun truck to something that into something that just for the track or fun outings. You need some big big turbos as the smoke is still pretty bad as 70psi in a 3b/40 twin package for a 370 injectors and a race pump. I was told that I would need about 100+psi of boost to clean out. I doubt that not to many people have done this, but man it would be a ride and a half. I think that I will just be happy adding nos shot to my 600rwhp ride to put the smile back on my face.
