Ready to do some damage for sure huh?! Props man. Nice N/A power. Planning on spraying by any chance?

Man that's kinda on the heavy side but still impressive. Any plans for weight reduction?

Yes nitrous will be added this year prob around 100-150

Bacon: for the weight I can really only do the front k member/a-arms but other than that there's really nothing else adding the n20 is cheaper too lol. Going to get a real weight check soon I think that scale was off at the track have to take a ride to a scrap yard for an accurate weight.

Nice results.. got me looking into vac pumps again.. seems like a lot of people don't gain as much as you did tho.. anything tune related changed for the dyno? Any more pics on how you routed your lines?

Dietcoke has gained something around what I gained n my buddy with his maxed out lt1 has gained around 20ish HP.

Looks good thanks for the pics. I'm wondering how I'd get the vacuum source now since I have Holley valve covers and I don't have that oil fill cap screw in thing anymore but rather a threaded oil cap that screws in. Might just have to drill and tap the oil cap I have now. I like what you did with the adjusting valve as well.

Also, for the 5ft line supplied, I assume you didn't use all of it, but do you think 3ft would be enough for how you routed it?

You should seal that dipstick off as well I've read you can still draw in air from there. Some people have taken an old spark plug wire and took the boot off and put it over the dipstick tube and up to the yellow handle so it seals and you can keep the dipstick installed in the tube still.

Might get away with 3ft n yes I had some left over its just easier to buy the lsx kit from Gz all pieces needed..... for your valve covers I'd just drill a hole n thread a -10 fitting in it my case I found this fitting on eBay from hawks third gen. Good idea on the dip stick thing I'll have to do that.

I agree with Jesse. Nice Results!! That vacuum pump with that kind of horsepower gain should definetly drop some e.t at the track and by the way that scale number do seem a bit off cause that's on the heavy side. I know you mention the k member don't forget about a front bumper support from mwc. That's another 20lbs off the nose for only a coll 150 bucks ;-)

Front bump support is gone lol

Are gains like this typical with a vacuum pump on head/cam cars? Or is this more of a stroker mod.

Depends on application i say and how much crank case pressure you are building.

Bacon: that's with my 160lb *** in the car too

Baconz28

If you don't mind me asking what style rollbar is in the car? Mild steel or chrome moly? Points?

Chromoly 6pt removable door bars

Is there a way to measure the crankcase pressure to determine if a vacuum pump is worth while?

That I do not know but I know

Joe...jump on Dez's dyno next time he has a dyno day to get a little better comparison. Not saying precision is a high reader, just a thought.

Evan already did a comparason with dez n precision there are the same

Baconz28

What you think the percentage difference between your rwhp and flywheel Hp?

That I'd have to research on what a certain lb clutch takes to spin/t56/dana60 with 410s if I were guessing 620-630 figuring a 60-70hp to spin everything. W.e. that is in percentage
