Wow, really? That's an interesting picture. It looks like they used MFR housings too. Well I have access to a 45 DCOE that just needs all the correct F tubes and what not for a P-port.

Thanks Mike! I think I'll go with the peripheral port option and save the large ported plates for another engine.

My -SE engine felt okay with no sleeves or actuators at all. The actuator rods take up a lot of port volume.

Grind?

They just slide out after you remove the intake manifold.

I mean the ones on the exhaust port! Not questioning you guys but in the Pineapple video when they put in the sleeves on the aux ports they bent some of the sleeve to make sure they wouldn't come loose, did you guys do the same? And really not questioning you guys got mad respect

my rotor looked almost as bad as that one. It also took out the "bridge" between the secondary port and aux. port on mine. I used a set screw, loctite (like they specifically stated at the time), and I bent the sleeve around it to make sure that it would not come out. It did last for 25k miles IIRC, but it did eventually give way and shoot back towards the pin. The sleeve never got sucked in, but the pin did, lol.

Tweakit says it better to go with the Haltec. What kind of hp would I be looking at just with this setup:
Large streetport
Racing beat Headers
These Itb's
Haltec x6c (I think thats the model)
E-fan
I know it won't better my HP but also;
a lighter flywheel
Racing clucth

What intake manifold? What are you doing for exhaust? Those are way more important.

RB only sells one type of intake manifold for IDA carb and one type for DCOE type. Which are you using?

They all require porting for best power.

Street port!

1/2 bridge has more benefits than full bridge on the street but less than the street port. That's why the early experts coined the term street port in the first place.

Sorry. I didn't realize this thread had progressed as far as it had. If you have already decided on the PP option maybe I can talk ytou out of it. I've done several 6 port street ports eliminating the aux. port sleeves and they pull nice and hard at a fairly low rpm. That PP is going to require some revs to see the benefits... not to mention the extra $$$$$!

What go you mean about PP, not doing a P port if thats what you mean, going straight street.

Could you talk more on those removals of the 6th port sleeves. Was that removing the sleeves in all together?

Streetport all the way! I have only found a little snippit of info on 1/2Bridge and for what its worth its a waste. Unless you are looking for all the downsides of a full bidge port with the performance of a streetport.

street will leave you with the ability to add forced induction down the road whereas the overlapping ports will cause lots of issues

if by NOS you mean Nitrous Oxide I think you would fry something using that on a bridgeport, not too sure to be honest but something tells me it would hurt the engine.

if your running strait pipes unless you are just removing the sleeves, id suggest wiring them open, as you wont be able to use the 5th and 6th port actuators. that other person must have had something wrong with his car because when i did this because my actuators were just i lost a little power below 3K but nothing significant, and between 4k-7k pulled like a bastard, ive also installed the pinapple racing sleeve inserts and it made a noticable difference, i used jb weld to install mine instead of loctite and i havn't had any problems
