Competition How do u get 500hp out ofa 12Valve?

[AWard]

Just lookin for a quick and simple explination on what needs to to done to get a safe 500-600 HP out of a 98 12 valve with 215 p-pump?

Quick and simple... turbo, injectors, cam, exhaust, transmission/clutch, head work, pump work. That "Safe" is a relative term. The new turbos out now have put a lot more safe into them than the previous generation turbo. The mechanical world isn't as "simple" as the electronic. There are good threads on upgrading the 12v if you do a search.

500 is easy anymore... DDP4's and an sps62... with a ported head I did 535 at 18. 5* timing. w/ some tight EDM's and more timing and a silver 66, I think 575 wouldn't be out of reach

 

[AWard]

How about with a stock head? Would that be impossible?

easier than you think. large single or twins, get the pump to a pump shop and have it tune (balanced, 4gsk,mack plug,dvs) and a set of 370s should get you there

Alright well on the pump, i know bout the 4gsk, mack plug... . Whats the dvs? maybe my mind just aint workin right

delivery valves, you prob wont need them but it helped get afew more cc's out of mine while it was on the stand. since you are starting with a 215 pump your stockers should be fine. the afc, mack plug, and gov is the biggest part of the pump, plus if it is balanced. everything in the pump needs to be matched to make it perform like it should.

 

[AWard]

Thanks... Yall are a lot more help than any other forum on TDR

No reason to pull the pump if 500 or so is the goal!



What is safe in your mind?? What is trucks intended purpose??

 

[PRattenbury]

Mack plug isn't gonna help on a 215 pump, IIRC. 4KGSK, more timing, fuel plate, and a new turbo matched to the output of the pump will get you where you want to be.

:-laf LOL all it takes is some more fuel and air:-laf And be sure theres a decent built trans behind it to apply that power to the ground or all that power is moot.

 

[AWard]

Im probably going to go with Water methenol just to keep things cooler... This a good or bad idea? And how bout the 370 injectors? would i be better off going with other injectors?

 

[pwerwagn]

I have some special edm 370's from Joe D, a relatively small turbo, a true 0 plate, gov springs tightned (just for the day of the dyno), intake and exhaust.

My #'s are in my sig. however, it wasnt safe power. It would hit 1500* in absolutley no time!!

 

[Forrest Nearing]

I would go with other injectors... I love my DDP4's and they're great at 500rwhp. water/meth will help power numbers and EGT's.

 

[hummincummins2]

injectors, turbo, tune pump and a smarty

^^^^^^^^^

12 valve:-laf

 

[WShupe]

I'm looking to break the 500hp barrier with a T61 and stock injectors fuel only on a '96 5spd.

 

[catoiler]

Pull it out and put a CR 24 Valve in!:-laf

600 with stock 370 injectors seems easy with my combo!
