Engine/Transmission (1994 - 1998) dv=? power.

[SBrandon]

Just installed my 3k gsk yesterday and liked the results, but now I need more HORSEPOWER how much power can you expect to gain with the installation of high flow delivery valve's?

 

[RBratby]

you are going to get a mixture of answers about this question. some of the guys say yes you do get some horsepower and some say no you dont get any horsepower.

 

[BPonci]

Delivery valves will give you more bottom end punch to get the turbo spooling quicker. I changed mine and felt a difference. Jason Burton dynoed a 65hp gain in valet mode. I can tell you your EGT will rise much faster. Good luck with your quest for power!

191 dv's

I just installed a set of those 191 dv's into my 215 pump last night and there is a good seat of the pants difference in acceleration and smoke output is easy to control. Boost comes on alot faster than before, i am very happy with results!!Oo.

With my 215 pump I dynoed 191s three different times, each time with new 191s. Also a set of cut DVs. Got from 0 to -12 hp depending on the rest of the mods. I use stock 181 dv's for the 800 hp configuration.

When I swapped my 191's for cut DV's with no other changes, I gained (can't remember exactly) over . 10 on my 1/4 mile ET; that's a horsepower gain. Lots more smoke and higher temps.

I don't know how much you can safely put through with a 3K GSK, though... I have a 4K.

Does anyone know what DVs come in a 215 pump?? I thought I read somewhere that 191s are alreayd inside a 215?

 

[Cooker]

181 Delivery Valves are stock in a 215 pump.

I'm just geussing here. But I would think the small hp pumps would feel the difference the most.

I have a 175 hp motor. I have 191's ready to go in. I have 370 injectors in right now. I can tell I need to get those dv's in soon. Kinda doggy till she hits 1200 rpm.

I'll confirm what Cooker posted. Had a delivery valve out of my 215 pump yesterday when setting timing. They are 181.

It's weird that Joe is the only person who has never seen a HP increase from installing a set of 'bigger' DV's...

Maybe his tricked out pump has the ability to overcome the DV restriction in some way?
