Well decided to bite the bullet and go with a belt driven setup off the crank to turn a remote cable drive pump.

 

Ordered a new damper from proffesional products so I can utilize the 3 bolt face and a drive mandrel from aeromotive. I will have to machine the hub side of the mandrel to fit the ls damper but thats no big deal.

 

Called up Waterman and picked up their drive spud setup and remote mount bracket. Will have to be creative as far as mounting it but there is room so I am sending the car off in 2 weeks to the chassis shop to fabricate a mount for the pump.

 

Picked up the waterman racing sprint 700 mechanical pump. it flows 6.8gpm so over 400gph and will maintain 100 psi line pressure no problem across the entire range. I really hated to put the money out but I know I will have a fuel system that will never need upgrading no matter what I do with the car and I no longer have sleepless nights in fear of one electric pump starting to fade off and lean my engine out while in the boost.

 

Anxious to get it all on the car when it gets here and then get it back to the dyno to see what my injector duty cycle is at and have brian add some more cranking fuel to the car so I can get it to start up easy until the pump is making pressure from engine rpm

 

will keep it updated as to results.

Mine was a alignment issue with having to run a v belt. If I could have used a serp belt with it would have rocked. The reg cog drive belt they use should never move. I like cable drives there is a dude on theturboforums with a puke green nova ls swap with one id see what he uses. Ill try and find a screenname but get on and search cable drive and u should find it.

Update on Cable drive fuel pump setup. Due to having a stock fbody balancer I had to get a new balancer to run the mandrel setup to run the cable drive.

 

I picked up a professional products balancer since they have a 3 bolt hole face. Then I got an aeromotive BBC mandrel. The two will not work together but the bolt holes line up. I took the two pieces over to Mike Rush at MM Head services and he put the mandrel on the lathe and made the two fit together like they were meant to.

 

Very cool how it works. I have a Waterman Sprint 700 pump on order (flows 6.8gpm/408gph) cable, drive adapter,mount and setup for belt up front on the way.

 

Still need to get a new weldon regulator then Ill be in business.

Both good and bad occurred today....

 

Picked the car up from chassis shop after having some brackets made up for some parts and then having some custom fab fuel pump things finished. The cable drive system is bad ass. Even sitting over night and with the tune untouched from the electric pumps the car fires up almost instantly or very little cranking.

 

Took the car over to Dynotune and had brian look at the tune (needed much work due to the new fuel pump) but its a good thing my injector duty cycles will go down by more than 30-40%

 

Got it up on the rollers brian worked with the tune a bit and got it starting real easy and made a couple pulls on the wastegate spring. 6 psi the car made 570whp which is a great improvement.

 

The bad:

 

Oil leak :( had to cut the dyno short until next monday. For some reason I reused a very old (150k plus) valley pan gasket and not sure if crankcase pressure took its toll or what but it started pissing oil from the gasket that was visibly pushed out. and Ive had enough of these valve covers also. I ordered a set of billet covers from Nasty Performance and bought a new valley gasket from the dealer today.

 

Overall it was minor in nature but still shitty, will be back out to the dyno next mon/tues to give it another shot..chasing the 4 digit whp number, feel pretty good now that the fuel system is beyond overkill and will never be maxed with my setup.

 

some pics of setup. I also mounted the coolant catch can in the trunk. Im going to run a -4 from the front overflow port on radiator to trunk so if the system ever does pressurize the water will be behind my rear tires

 

And also bought a kurt urban vapor system and had a custom mount made for the box, still need to run the lines.

Lol I don't think there is a problem one with the motor it's just venting crankcase. It's an age old problem on these cars. Alot of big power cars run a vac pump to pull out the covers. I just need to decide to vent valley cover or not. The only place it leaked from was shitty valve covers and that was because of not being able to tighten them with the all pro heads

 

The valley gasket could of been weak, but I'm

Not naive to think it also gave way due to crankcase pressure just need a solution and it's hard to get concrete info

 

 

How was yours before dry sump?

man I would love to have a dry sump, but Im done dumping money at this point, its been a long 2 years for me.

 

My plans are to put a -10 inside of valley cover and build a baffle tray underneath it do oil cant just get sprayed directly into it and hopefully it just acts as a crankcase vent without to much misting.

 

My guess on my setup is with the manufacture ring gaps for boost and running e85 on high boost my blowby is more than the 2 -10 valve cover vents will take care of. Either way I will give the valley cover a shot if it creates to much of a mess ill put a cap on it and go from there

^possibility. I dont really think the blow by is an issue. I think I just need to figure out how to get it managable under boost. Im going to try this valley cover vent, put everything back together and go back to the dyno early next week. If things go south again Ill just take my time for the rest of the year going through some research and try it again next year. I have accomplished alot in 2 years and starting to get burned out and tired of spending $

Amen. I didn't mean to mess with your swag -- love seeing updates to this project!!

 

Not sure if you are keen about oil/mist being introduced into the intake track (or exhaust), but you can size & place a venturi in-line with either to use an el natural vacuumn effect.

Ended getting a bung welded in breather and the vally cover, then welded a little tray under it to shield oil misting. Hoping to just help breathing under heavy boost pressures. New valve covers from nasty performance will be here Monday then see how it goes.
