Would anyone be interesteding in sending their intake manifold and/or header to Extrude Hone? Its one of the most advance port/polish procedures out there. Instead of doing it by hand like everyone else, they hook all the open ports of your head or intake manifold to a maching that forces a thick, rough gel-like mess back and forth and back and forth through the piece. This material is like liquid sandpapger and it will smooth and bore the entire thing, in do it the most where there is the most resistance. It should be like $300-$400 per piece to get done. I think I can get us a core for them so we dont have to lose our cars while the process is being done. Anyone legitimately interested for that price?

bump?

 

2-4 weeks, hmm thats alot of time with out a car. whats the price difference between that and manuly porting? cost vs. performance on either

 

yea, im gonna get a doaner core so their is no 2-4week wait, u get the new one, swap out, send ur stock back. manual porting may be $100 less, but wont be as effective

 

Why don't you do the first one and then sell it with a requiered core exchange and then just keep it going that way so there is no delay.

 

thats the idea. just dont wana drop that kinda cash if i dont have to. but if enough ppl are interested, it would be worth it. who would be interested?

lets assume the following:

1) it will have good results (IE: increase of ~10 WHP. we may even see more, but i think this is a safe guess. SRT4's see about 22whp from it!)
2) the cost would be fair (IE: ~$800 for the combo)
3) there is a core exchange program so you dont have to wait without a car while its being done. I would need a holding deposit, though, to do this.

To get a single head done, EH asks $600. A 1-piece intake manifold is $485. I am pretty sure I can bartter lower. I'll talk to the mgr and see if we can make a deal /w a recharge program if I can get the cores and keep asteady flow. If I can swing a big enough discount ($~800 for the combo), who would be interested?

1) me (blk-majik)
2) ...

 

It sounds like a good idea. But it would be nice to see what kinda results can be attained from this process first.

 

yea, ill dyno first. i already have my baseline done, so no guessing what actually happened. 2nd weekend on March if things go fast enuf =) but thats what im asking.... if there is interest, ill use my tax return to buy the cores and get them done if i can swing a price deal. then i'll dyno. then if my end of the deal holds up on power and price, anyone else could do it. just wana guage the interest IF the results are good.

 

just got off the phone /w the auto hone manager. Here is what I can swing:

He can do $850 for the Intake and Head (or seperatly at $500 for the head, $350 for the IM). That is a savings of $285, and you dont have to have your car undrivable for a week or so while the work is being done! They say that a group buy rate applies if you get 6 done at a time. THey are willing to work with me and do 1 at a time, but if we keep the flow relatively steady, it wont be a problem.

If we do a core exchange, they wont manage it. I would have to manage it. That is, I go out and buy a spares intake manifold and header to start with. You buy it from me. I send my spare to get done for you and they send the finished product back to you. When you get the new ones installed, you send me your old stock ones.

Obviously, the big question now is how much power will it make. I'll see if i can swing a test run on 1 unit and find out myself if you guys are interested.

I also still want to find out how long the turn around time is for them. The website says that it usually takes about 2-3 weeks to finish.

btw, our intake manifold is aluminum, as far as i can tell. I think I was priced for a EFI intake. The N/A intakes are cheaper =) i'll mention it when i call him back.

And by looks, our exhaust header is cast iron, right? i think he priced me for a aluminum header. It is iron, no alum, right?

I'm not sure if gasket matching is included, but its listed on the price sheet for an extra $80.

 

Thsi might be a dumb question, but if you get this done, is it still possible to turbo your engine later on? Would this affect that in any negative way?

 

yea its still very possible and would help alot /w the turbo. BUT, only for the intake manifold. you would have to fab a new header to feed exhaust into the turbine. Thus, u replace the stock header. since the turbo is focing more air into the intake, doing this to the intake manifold would REALLY make a big difference (assuming our intake manifold doesnt already absolutly kick ***. at the price we paid, im pretty sure it doesnt).
