Rob, it will depend on how you turn-up your pump. Its not just the sticks on the P7100. You could try a bigger single like around 62-64 on the compressor side and use methanol/H2O spray. You could a little bigger on the turbine side, if you tow. I used a GT3782R as a single and it worked decently. Thats a 63 inducer. My spool-up was as good or better than stock. A bucks down twins is your stocker (with a smaller turbine housing) over that 3b. You'll drop 200 deg's. I have to work real hard to break 1000 deg's on this set-up. I started to mix some 100% methanol hydrate into my -45deg's windshield. Wow that put some pick-up into my acceleration. I'm gonna add another nozzle down the road.

oh ya the tuning is big , but i am thinking i will need more turbo just to let the hot stuff out , i would love to put a gt3782r on my truck but they almost the same price i payed for the truck . but we will see what i end up with , never know , i was thinking of rebuilding the garret that is on the wall at my place and using it under the wh1c , see how that would work , it's a smaller turbo but much bigger then the stocker , well i will just have to see

Wink, I just wanted to give you another option buddy to think about. I do have spare one kicking around in garage. I want to throw a K-31 under the GT3782R with a decent sized 42mm external gate. Its just time right.I got a good deal on that turbo, if you look around, you can find one decently priced.

I'll have to get those rebuild kits next week for ya so I can get you to work
. That 3B is a good twin turbo. I feel that the 3B lites harder than my S475 does. The S475 does spools up faster, just doesn't have the ump as the 3b did. Don't ask me why, as they are very similarly sized turbos. I have to try two different primaries to see which is the best.
I get bored easy. I've give the smaller twins turbos shortly and will let you know what I think. Then I try a mid sized one.

thats kind of why i was thinking a small set of twin would work well , but i will have to see , i was thinking hx-35 and this mid size garret i have but i have to find out what size this garret is ....
[QUOTE=Lil Dog;2607629]You think that would be an upgrade worth doing for this setup? All I know Rob is this S300 is too small on the hot side.

Rob, I think that you'll have transmission or clutch issues before you'll run out of air from the 3B. I ran 670rwhp and towed with the 3B turbo. You guys can easily just adjust the pump to reduce the amount of fuel that you'll have available and still use the big sticks. You look at Brandon truck at the last GTG, he's running a similar twin turbo set-up as to your twin build up. I think that you'll be pretty happy. A few guys have done runs over 700rwhp on the 40/3b set-up running a P7100 pump. Its a good twin set-up and will be hard to beat.

dog, how hot is hot? I'm sure that you can drop two to three hundred degrees with the right primary. Sorry buddy, but I couldn't help myself. Twins go on pretty easy. I'm game to try.I'll take them home if it doesn't drop the egt's.So far my favorite primary is the BTH-3B.

I thought that there is two different types one mechanical and one electrical. I want to look at it to see. I have a garrett similar to yours, but the VGT part is done by oil pressure and you can't rotate the housings (unless you do some machining). I haven't used the turbo yet, as the turbine housing is very large and the compressor inducer is very small. Not a good combo for big power. I do know someone that has one of those holset 351VGT turbos, so we can take a look see at it. I saw a bunch on ebay for around $200 off a 6.7L engine
