whats the max hp on a build but not exotic motor combo i am trying to decide if i should start a new project or keep pushing this one, if there is not much more dependable hp left in this combo i might try something new. i dont have the money for a crazy exotic motor combo.
right now i am running a cmotorsports built 408. calies crank. oliver rods, je pistons, afr heads, arp everything. i see it is a prety basic but stout combo. no crazy oiling tricks or one off girdles. i am over 1000rwhp with it and have made ~50 passes with it at around the 1000rwhp level and also put at least 6000miles on it in the last 6 months. i tried adding in a little nitrous and didn't have the tune just right and messed it up a little but it will be back up and running soon.
with more turbo how much more hp might this set up be able to support without a lot of maintainace. with my driveline i am probably around 1250fwhp now. the turbo is rated at 1250 and it is definately spent.
if the consensus is there is another 300+more hp left in it with more turbo and a dead on tune then i am going to keep on going with the project for another year. if the consensus is i am at or near the limit now i need to come up with a new project. if i can't make it faster then it is time to move on.
i guess a good question would be is there some more basic mods i can do to help it survive more hp without spending crazy money. if i keep going with it i am thinking about going with some big twins and working on my 60' time too. i think it could see mid/lower nines eventualy.

I've been real impressed with your results. More turbo, more tune , more power.....go for it....have Jose spec a turbo for 1500rwhp with your combo. I'd bet the engine holds up with a perfect tune.

i think chuck from finishlinetrans would like to see me keep pushing it. he gets all excited(happy) when i break something. he really seems to enjoy finding the weak link and figureing out a way to get rid of it.

I'v been folowing you on 1320video and I've got the drag week video, and I would like to see you push it alittle more. stay with a single turbo but go bigger....

I wouldn't call my old motor exotic.
stock block, crank, and main caps. crower rods, je pistons. studded, 317 castings on the heads.
Yeah, solid roller with a carb manifold, but the long block was nothing special.
Only thing that might count as not normal was the drysump.
Then again, the white TT car we ran in 05 still had the internal oil pump.

if i may, didn't you mention to me at one point that you were running up to 3:1 exhaust/intake pressure? wait and see on my new combo; but right now it looks to me like your turbo is holding you back. i don't know what your IAT looks like, but precision just came out with a new line of air-water intercoolers that are smaller, cheaper and more efficient.
give jeff @inductionmotorsports.com a call; he's helped me a ton!

i was seeing a 3-1 when i had the t76 on there. since then i have the 88 wich has a much larger turbine and i have a larger down pipe. the turbo is holding me back but only because it has reached it's limit.
steping up to a larger turbo will surely give my more hp potential and that is my plan but before i do that i would like to know how much more power the engine combo can reliably take.

I think you will be getting a little close to the limit and being able to drive it everywhere on that combo. I would imagine another 200hp or so and mid 9's and you could still drive it, but I think its gonna be a little close to the limit in the words of reliability.

MS is more powerful than alot of the early 90's OE computers.

now you've done it! lol
Jim keep the truck. you've got a good thing going, and in my mind a gt47 with a nice 5" downpipe will give you at least 150hp. that combined with the reduced exhaust gas pressure in the manifolds should make things a bit gentler on head gaskets too. at least that's my philosophy; who knows if it's right.

sequential is being worked on for MS, and thats the only real way i would say BS3 has the upper hand at thoose power levels, however im no mod and i havent yet started my build up. Once Brains get done with his portion i feel that alot of people will go the MS route, for extreme HP.
