Well I've made it home for the summer and it's time to start tearing this thing apart. I will begin tomorrow, but yesterday I took it to the dyno. Laid down 503 / 1215. I was very pleased with the numbers, but the knocking is getting worse to it's time to take it apart.

 

For the rest of us, what is that thing?

Vacuum pump shaft seal ..........the thing between the VAc pump and PS 

Yea... Exactly correct.

So what made you pull it out if it wasn't leaking ? 

On your last dyno ...... What was your secondary turbo you were running ...... And what boost #'s.

when are you hitting the rollers with new injectors ?

 

I've got 8K on the motor now, so it started leaking a couple thousand ago.

Secondary is an industrial injection phatshaft 62/65/12.  Not sure about boost numbers. I was watching RPMs.

I still need to buy the injectors......

Going to "try" and get mine on the rollers sometime before Xmas. Then going to start a plan to build out to 1000 hp. Honestly don't think I'll make it (1000) and might not happen anyway $$$ .... But wife said "ok" ;) 

have a similar Air setup now 63/71/14 over 475/96/1.25 hence asking boost. 

Hope to make 650-700 ...... Then I'll see about new engine build ;)

Dude... you drive a lot!! haha

It's been intentional.... I'm trying to get miles on it so that I can switch to synthetic over Christmas! Currently been putting on close to 500 a week!

1,000 is going to cost some money.... I wouldn't try that on a stock bottom end.

You've got a much looser exhaust side than I do. Elevation SUCKS

How much HP can a stock engine hold up to? All I got is ARP studs

From what I've seen the rods start to bend and break around 1,000. @ 900 you're pretty safe depending on how much torque you're making. 

Keeping the head on usually requires studs and fire rings.

Sounds like I got nothing to worry about then, I was thinking some day 600-700hp would be nice.

700 is unlikely on a VP. With a HO VP it's unlikely you'll make it to 600. If your VP happens to go out look into a SO VP.

I've ridden and driven a 725hp 3rd gen... It's crazy when you can blow the back tires off at 50mph with 285/70/17. All it has are studs, twins (62/75), an 85% over cp3, 100hp injector tips, UDC tuning by me, and a south bend dual disc.

Monster mike VP about only way to get over 700. Kinda doesn't count though ;) Well they all count ..... But to say it's a VP 

Stainless Diesel went over 1,000 HP on a VP44 pump.

 

thats Mikes pump

Also a VERY unreliable pump..... I think Industrial's dragon fire goes above 700, but again reliability sucks.

Used to be ....... supposedly much better now. 2 cents from what I have heard. 
Problem has always been getting in contact with Mike for issues. I run his transmission and its awesome ....... and he told me (not original purchaser) that if I ever broke a hardpart - he would replace it free of charge ...... pretty cool - but will see if it ever happens.

But to your point - a 700-1000hp VP is not for daily driving anyway   Not saying it cant be done .... but .....

I won't be the one to test that theory  Going snowmobiling and having the pump crap out in -20* weather wouldn't be much fun.

I can't imagine they're very fun to DD. Heck that one even has top feed injectors!

I think I'll be happy in the 600's. It's hard enough keeping the tires planted in the cold!

Yeah agree.

Actually if I shoot for high HP it will literally be a dyno deal. Ill change the secondary and the injectors to something larger ....... and dyno. Then revert to smaller injectors and secondary for DD.

Problem I think I will hit will be the primary however ...... s475 literature says will get to over 900HP ..... but seems most step up to a s480+ .......

I think you could with a CR, but given the limitations of the P7100 stepping up to a larger primary would probably make it easier.

Had my dad drive it last night. He believes the driveshaft is out somehow. Hopefully get it balanced tomorrow.

Rolled over to 8K on the motor last night!

 

Get it balanced?

 

8K.. wow!! I just hit 20K on my rebuild yesterday and I have had it back for almost 2 years (2 years on 12/10).
