A flow through? Definitely better than option b. Cycles more coolant

Or is that an ice box?

 

If your gonna run a flow through, pays to run an ice box, IMO.

 

Are both of you guys planning on 91/93 pump?

 

For now yes. Need to see how stable E85 is here first. Places have stopped carrying it and I don't want to be stuck because of that.

 

Yeh, E85 is not widely enough available here for DD use.

 

Bummer

 

I did a compression test today. Cold, without remembering to press the accelerator at all like a *******, with 4 revolutions I managed just under 145 per cylinder except #2, which was like 137psi? I want to redo it and effing remember to depress the accelerator though...

Anyway, I began work on porting my blower today. Opened up the neck of it a bit, and gave it some more throat where the rotors meet the neck. Got rid of this annoying ridge:



And if I'm going to have my tools out I may as well port-match the manifold too.



May consider polishing the outside of the case once I'm done porting.

 

I might have to take you my manifold for porting lol

 

Lol let me experiment more. I think I've found a tool that will let me port the entire LNF manifold instead of just the runners. We'll find out soon.

 

Your port work is impressive. I might need to get my manifold ported

 

Sounds like a plan to me im not in to much of a hurry

 

Really? I thought it looked like **** because it isn't absolutely flawless

 

Lol i think it looks pretty good

 

what tools are you using to keep the supercharger inlet even? or are you just blasting it with a dremel?

 

Air grinder, sanding drums, and a very quick and steady hand.

 

I've been considering a flex hone in a very rough grit (under 120) for this to keep the porting even to reduce the risk of taking more material off on one part and changing the shape of the inlet, just not sure how much material it would wind up removing. Obviously wouldnt work on changing the port size for the LS4 throttle body much that would have to be done before hand.

 

If it were a more circular piece I would have probably done it that way but this supercharger is all over the place. Especially when I get the throttle body, a huge amount will need to be taken off the bottom and none of the top.

Flex hone is a good idea but often when porting you don't need an even amount in all areas taken out. You need more here and less there, especially with port matching on these cars.

 

Finished most of my porting today. Now the manifold just needs a good cleaning and some new laminova seals. And a dual pass made for it. Hopefully will be doing that soon. I booked a hotel for a couple days during my little brother's spring break so we can see each other for the first time in almost a year. Soooo, car funds will be slowed down a little bit. Honestly I'd spend $315 to make my brother feel cared about instead of blowing it on my car any day so it doesn't bother me. I'll just do the free/cheap stuff for now. Getting a phenolic spacer and IC pump/brackets will give me stuff to do anyway. I may as well mock it all up.

 

Got my phenolic spacer today from a 06cobalt_racer! (I think that's the username?) Should be getting my IC pump and brackets allegedly tomorrow from sandman. Getting this **** off the ground!

 

I realized that i forgot to put the pump pigtail in the box so Hopefully I remember and will get that mailed out to you tomorrow.

 

Eh I may already have one anyway. Let me see if mine fits and we can go from there.

 

mine is the full pigtail to the add a fuse so no wiring would need to be done. I'll still try to get it in the mail tomorrow hahaha

 

Cool I appreciate it. Least you don't try to screw me over and keep me waiting like the guy I bought the SC kit from.

 

I got your back bro.

 

I promise to make a lot of power. And maybe accidentally blow up my motor
