Intake and flow bench

Re: Hustler 500efi engine tear down & Build Up
 

Ck out the valve job . The new design seat cut that Mark at Precision Marine came up with has a lot of extra radius's and angles .It blends everything in together. With what I did in the chambers and below the seats there is NO extra work after the valve job to be done. The old style cutters use to leave a ridge and most shops would not go to the trouble to do the extra cuts and then dress the chamber lip. We also did the extra cut on the intake valve . He should be finished with flowing the head Wed and I will get a print out on all the #'s. :D I am guessing I might of got about 10% at least I am hoping?If not I will make it up artificially :evilb: :evilb:

Just think this was on just some old 088 cast iron heads .What a waist of time :drink:

Well I got the Whipples in and I could not stand it I took this one apart :eek: :D Ck out the vacuum fittings on the inside of the lower . They had little aluminum flakes coming off the treads where they cut them and didn't dress them up. No biggie :D

Before final assembly on the heads I wanted to mock it up with the lower intake to ck intake to head face angle . To make sure the angles where OK . since the block had been cut so much and the head cut a little I wanted to make sure . Remember in the beginning of my tear down the leaking intake gasket. Wanted to make sure it wasn't going to pinch it.

Re: Hustler 500efi engine tear down & Build Up
 

The other reason on mock up was to ck port alignment and to trim the intake gaskets . It was off some . I guess core shift in either?

On the openings there is some ridges left after machining. Probably might not hurt flow but it cant hurt to smooth them some . Mark had already told me about this before we ordered the kits.

The kit looks Impressive !!I haven't even unpacked all the boxes of stuff yet. Its going to look good sitting on my old hand grenade motor :evilb:

You want belive the innercooler core in this thing :eek:




One thing that is bothering me is this unpolished bearing[seal] plate,that has the serial # in it.

Re: Hustler 500efi engine tear down & Build Up
 

I see you have the same cylinder head porting kit I do. I thought I had the only Bud Light kit on the market (Post188). After that iron intake, you need some hops to wash it down.

Great pictures, keep them coming.

Re: Hustler 500efi engine tear down & Build Up
 

Looks great Rob, take that unpolished bearing plate and paint it black to match the motor, tape everything else off, thats what we do on our harleys, the middle ring on the rocker boxes, adds a touch of detail to it...Rob

Re: Hustler 500efi engine tear down & Build Up
 

Yea I had a lot of iron Intake on those heads.Linnie it helps with the cutter :drink:

Rob the bearring plate is on the inside of the timming chain cover.It want show .The paint would flake off anyway

:D

Re: Hustler 500efi engine tear down & Build Up
 

Can you post a few more pictures of the intake lower, especially looking down into it and also of the upper and intercooler and how it fits together. Thanks.
