Remember up and back with the crossmember.

Yeah, that's what i've read on here! Heard she needs a little bfh help though:bang

You'd think as much of a pos as the stock trans is in these trucks you'd expect them to design an easily removable piece ha! :hehe:
 
dont know if what I run is a comparrison?
I run a C6 tranny behind my 12v
It has a custom made 1400 rpm stall convertor - and because it is pre-overdrive etc, has no lock up
My 71mm turbo has no problems lighting at 1400-1600 rpm, on the street or on the track
 
:Cheer:

What are the specs on that charger? 71mm comp? If that converter only flashes to 1600 you may have the quickest lighting 71mm turbo in history lol

Timing has a lot to do with it also, as well as porting/cam etc, etc.

I know a friend of mine has a heavily ported engine with a big cam and he can light about any charger we have put on it!
 
I use my factory Honda scissor jack and a block of wood to spread the frame, works great!

Goin to be swapping in the new stock stall speed converter from Goerend this weekend. I hear the crossmember is fun ha! I'll report back on how it goes, thinking it should really make this charger alot more fun to drive and race!!!:ft:

I'm hoping I can get mine changed out next week for a race on Oct 4. Going from a Suncoast 38-3d back to there 19-3d. I think the looser converter will help me as well.

We got a Harbor Freight bottle jack and welded a piece of 1 3/4" d.o.m. to it.
 
i ran a DTT 89% single with a 1400 stall and it would light my smaller twins but not the new set..... now i am running a Redline Diesel 2200 stall triple disc and it works great

Man these converters are fricken tuff looking!!!!!!!!!!! When the trans went in the first time I never saw the parts as Brett at TNT did the install. Ofcourse this should come as no suprise given the amount of power and mass we're talking about here. I fricken love diesel race trucks lol:rockwoot:LOL

P.S. The convertered showed up yesterday.

So without spready the frame is it really that hard to get the cross member out? Maybe I will see what I can come up with.

I have a friend that doesn't spread the frame, he gets them in and out everytime. Walk it in from the back and keep it up.
 
nicktf - no idea - it is called a Pro52 by Holset
Goin down the road it will show 5-8 psi boost at any hill in the 1600-1700 rpm range
and under load it is like a light switch - 52psi boost all in n done at about 2200-2300 or so rpm

keep in mind I have a heavily ported head, manifold, larger valves and a big cam and is nite and day difference from last year with a stock head and cam where the turbo didnt really start to work/lite till about 2500 rpm

the other thing maybe makes a difference is I am runnin a VE pump which fuels really hard down low in the rpm band unlike the other pumps do.

Does it actually fuel harder down low, or not needing added timing for the big RPM help the spool. I can't imagine anything fueling harder down low than my 13MM pump.
 
mmm timing is set at 18 degrees static and has 12 degrees internal mechanical advance - soemthing a p-pump doesnt have

depending on the fuel screw setting I have up to 435 cc's from just off idle and up to around 2200 rpm and unlike your p-pump I lose most of my fuel by 3200 rpm being down to about 250 - 260cc's

is also why I am switchin to a p-pump this winter - I need rpm and power up in the mid to high 3000's rpm to stay competitive with the Duramaxes

I don't think I can get my pump down to 435.
 
Id say the timing is making the difference on a VE pump. But i doubt if the VE will fuel any harder down low than a P-Pump.

As for the crossmember. I have done several and never spread the frame on anything. A decent hamer will get it done. Just go up and back with it to get it out. Just mess with it and you can feel when it loosens up some and will move easier. Its not a bad job.

X2. In my experience timing makes a HUGE difference on how the turbo spools.

We have pulled my crossmember out several times without ever using a jack.

How much timing are you running Nick?
