Peripheral ports

Quote from: jackaleks;787025centrifugal superchargers (i.e. Rotrex) are basically belt driven turbos and have the same boost delivery, i.e. it gradually increases. obviously there\'s no boost threshold so you get positive boost quicker than a turbo, but compared to a roots or twin screw which will delivery full boost near instantaneously.

you want one of these babies!

whipple twin screw!

And have a car that looks like this? No thanks, looks ugly as sin in my opinion, and I don\'t want my car looking so obviously blown.

Not saying it\'s not cool, because it is, it looks awesome, but it\'s just not what I want for mine. Besides, I WANT a gradual power delivery, I don\'t want an instantly-on power delivery, I want my car to be easy to drive around town without having to ease the throttle 1MM at a time just to not be speeding.

Quote from: Grant Monkhouse;787031Lacey if your running pps then you won\'t need a third fuel rail as your throttle bodies should have the 2 injector holes each. So you can run 2x550 and 2x1680 injectors or which ever you fancy.

I have seen carls TB and they\'re prety awesome, I\'m sure if you rang him he would send you a picture of them, so you would know what your looking at for setup. You could do it through an apexi ecu too.

Really? I would have thought a third fuel rail would be on the cards, but 550 primaries and 1680 secondaries does make more sense and will be cheaper to do than plumbing in a third rail.

I\'ve been to Carls before and seen his oldskool drag motor, DAMN that thing is mental!!!

What I like about the supercharger plan is that my OEM EGI air intake system that I\'m still spending hour upon hour polishing the crap out of will work with the supercharger (probably require some work on it though), so it\'s not something I\'ll have spent ages on only to be chucking later on in lieu of something else, since the throttle body on it is a nice size and it has the 4 injectors obviously already on the upper and lower.

Pft thats half cooked

This is how to supercharge a car :god

I find it funny how tII owners try to keep specific parts specifically from their car for future modifications. Air filters, top mount IC too. Lol.

A third fuel rail wouldn\'t be needed unless going for massive power.

You can also move around the hp and increase the torqueof a PP by increasing the length of the inlet tract. I also think you would struggle to keep the top mount IC because you have to build a plenum for collecting the air forced in by the SC

I have seen the YouTube video of that car! They actually managed a pass with it, it\'s a blower from a diesel train. They mounted it and blipped the throttle which lifted the wheel off the floor by 6" and blew both metal head gaskets! Now that some serious psi!!!!!

Haha yeah, the bloke stood there talking matter of fact about it

Haha, we probably have enough old bits lying around to built most of a T-II from scratch between us (Prof and I) XD

Nah, not going for massive power, driveability would be nice so I\'m only really aiming at about 350ish hp. Once I\'m there I\'l probably get bored after a while and go for more, but that\'s my current goal. PP\'s and a Centrifugal blow running middle PSI\'s I\'m hoping will be in the mid 300 mark round about, and still be an easy car to drive.

Hmm, that\'s a fair point actually, may have to consider swapping in a T-II intake so that it has a collection for the cold air feed from the TMIC, hadn\'t actually thought of that until now. But anyway, this is still at least a couple years off and plenty of time to consider all options ans figure out the most successful

It wouldn\'t be practical to try use any kind of Intake as it will become bulky and possibly restrictive, a plenum would have to be built for you.

I can hear that \'ka-ching\' noise echoing from some of the traders already. :p

Ha yeh, don\'t want to put you off but your looking at custom stuff really. Just find yourself someone that\'s good with a tig welder and metal and your sorted. Or learn yourself?

Think I have answered my original question as to why most people don\'t run PP\'s, all the custom work I volved takes time and money if you don\'t know the right people to help build things.

Grant Monkhouse · September 07, 2011, 06:02:28 PM

Is there not any other people running PP\'s then? Other than the handful I have already listed, plus Ed and his new PP motor?

Quote from: Ed_RX7;787005mine will be ready in a couple of weeks;)...a POWERGAINS PP witha twist!!!!...watch this space!!!:burnout

I already heard about it at rotorstock 8. ummmm Really looking forward to it...

Quote from: Grant Monkhouse;787018Wait so after syed saying he doesnt like PP\'s he could well have a PP turbo in the works?

Well that is the way I would have gone to gain the magical 1,000hp he after. Hope he\'s prepared for some massive noise then!

Grant, its all in the pipeline. We are working on the paper at the moment. Soon, the action will start. :driving

hes mentioned they are bigger than revolutions ports which were semi pp, so im guessing hes gone down the same route, maybe a large street port on the plates and small PPs on the housings.

Could be running them independantly so they open at higher rpm like i have seen before, or could be running them all the time, but its doubtful

I would have though he will be running JAY-TECH manifold like so

Grant Monkhouse · September 07, 2011, 07:58:47 PM

Ye iv seen those before, there\'s a good thread on rx7 club of a 20b na with semi PP\'s achieving big hp. And the semi PP\'s are dragged open so to speak, by the engine as it gets to the higher rpms where the airflow is needed. He is currently working on some slide throttles as opposed to butterflies to gain back the loss of air flow from the drag on the butterfly.
