Porting

[Jim Nolan]

I was planning on pulling my injectors out and sending them off and was wondering if anybody knows of good place to send the plenum and injector housings for port and polish?

Jeffvette and Locobob, you can get them ported and powder coated for a great price.

Just to be thorough, though, DRM has this option on their website, as does Marc Haibeck. DRM is around $2k, Marc advertised $2,800 though that includes the labor removing and reinstalling, plus tuning the car in person. Might be a little less if you mail the stuff, you'd have to ask him. They both include a ported TB as well as a tune (obviously a mailed tune if you ship your stuff to them).

Jeff and Bob sure have the bang for the buck though if you want just the plenum and IH's ported and you can get them powdercoated for a good price too. I assume you'd want to get a tune done somewhere afterwards, though.

As others have said there are some good choices for the upper P&P.

I did want to comment about you "sending the injectors off". There has been more than one person who has regretted spending the money to clean and calibrate them as opposed to replacing them. I imagine it can work out ok at times, but there have been enough stories of having to spend double the money to strongly consider replacing the bad ones from the get go.

I agree , with z factor . our injectors were designed before oxgenated fuel whicjh mess es them up I got rc s wasnt cheep but they are a good durable inj. I don't know about the accels which are 1/2 the price of rc but i haven't heard anything bad about them. But oem inj suck IMHO:mrgreen:

I do intake porting Jim, here is some of my work: http://www.zr1netregistry.com/forum/showthread.php?t=1128

Jeffvette and I offer a package deal that includes intake porting and powdercoating the intake parts and cam covers for $1200. Let me know if you are interested or have futher questions.

P.S. Don't have the injectors cleaned - it just screws them up. Been there, done that, ended up buying a new set.

[ArcticZR1]

That is a really - really great deal on that package!

Sending my my plenum and injector housings for port and polish to Locobob along with Jeffvette's powercoating (to include the cam covers) is my next project for this fall/winter.

Will anybody be at BG this May with an example of Jeffvette's powdercoating?

Which color is that one above?

[guinnessdood]

P.S. Don't have the injectors cleaned - it just screws them up. Been there, done that, ended up buying a new set. I have been there and done that as well...don't bother getting them cleaned/tested. Either buy a new set of RC's or a set of Accels...which are about 1/2 the price of the RC's.

That's the silver color that I've been doing for everybody.

Airflow Testing
Is a control of each entrance made = 16 verifying the aiflow?
or alone a test is made with a ball of 36mm.

[bradslt5]

I believe they use the ball method . to run the whole thing on a flow bench would add alot of cash to the cost. i doubt thats there is 2%difference in them using the ball method

And he does mean everybody ;)

[bobbyhi]

Well, not everbody. I just sent Jeff mine to powder coat in "Artic White" to match the color of the car.

[cuisinartvette]

Flowing parts on a bench is pretty cheap, the problem is making the fixture to flow the IH and plenum, that would take some time and most shops wont be willing to do it unless you pony up. If ports are siamesed flwing doesnt make much sense at that point to get a true reading...jmo..

[bradslt5]

I agree wouldnt you have to make a divider that would seal each port in order to get a somewhat accurate reading. and even after that it would be a guess?

[Locobob]

Flow bench testing really isn't necessary unless maybe you are playing around with different port designs / configurations. The basic ingredients for a port job on a lightly modded 350 cid LT-5 are pretty simple: 36mm plenum ports, 36mm ports at the top of the injector housing, taper down to near stock size at the bottom of the primary runners (unless heads are ported), remove most of the huge primary injector boss (90-92 only), port match plenum to injector housings. Port to port consistancy is maintained by frequent measuring with telescoping gauges and or ball gauges.

Flow bench testing really isn't necessary unless maybe you are playing around with different port designs / configurations. the top people in the industry right now, Pro-Stock & Cup, hardly even use dry benches these days. way too much going on for those to be relevent. wet bench testing on the other hand :thumbsup:

[cuisinartvette]

Did this just today...The intake port (on the left) alone took me 6 hours, and its still not 100% done, probably another hour or so left in it.
