PORTING (making sense of it all)

Should I start the FAST FD thread here where it\'s measuring some quick in gear times for road going cars, using a VBOX?

Yes please. It would be nice:King

Yes please. It would be nice:King

No problem, I\'ll get on it, what section is best?

[Mir]

General and Technical. We can always move it to the other section by requesting to the relevant mod.

It\'s just a suggestion:

can we have a breakdown of info please just like the first page of this thread. For example:

Such Rotor Midifications can be carried out:
S4 low compression rotors
advantages: xxxx
disadvantages:xxx
To what extent it can be modified: xxxx
Why you can\'t go above such modifications: xxxx
Good for what sort of an engine: bridge port, street port etc etc
Things to avoid when modifying them: xxxx
Advise regarding Re Build gasKits for such rotors:xxx
Advise regarding Apex Seals when using such modified rotors: xxxx
Advise regarding boost figures: xxx

High Compression Rotors:
As above explanation might help.

it may be I, but I tend to understand things that way easily.

edit: I know it might be alot to ask but it helps alot when compared with understanding a whole paragraph which includes engineering terminology. Too much for a layman to understand :-(

That is a good idea, lot of work to do it though, and the "comments" would be :guinness

Maybe you can start a thread using the format you like above and others with "comments" can contribute their seemingly endless knowledge on all topics :Typing

Quick question what engine oil do you use and what would you recommend ,  mineral or synthetic oil,

I was just reading that thread!
hahaha *stalker*

[787b]

im very interested to know what people run when you see the amount of money and time spent on building these engines :Thumbs-up

[787b]

im not stalking lol  just been reading this complete thread which is very deep and wanted to know what your views are on  engine oil and what types :Thumbs-up

[re japi]

umm... :/ i just dont get it... lol

Still, this is awesome topic. I can learn lot from it...

Btw, Mir. I just looked "My Dream Project: http://www.rx7club.com/build-threads...roject-970923/ ". That thing is AWESOME!

Btw, Mir. I just looked "My Dream Project: http://www.rx7club.com/build-threads...roject-970923/ ". That thing is AWESOME!

one day I will have such sort of an FD. I am working towards it and currently buying as many things as I can.. Once my shopping completes, I will break my car and then rebuild it to such standard. If you meticulously read the build thread, you will see the amount of money that has been invested in that project.

In my opinion, no fd compares the Chips fd-end off. It\'s my dream fd. However, I do have a reservation on the body kit used thou! :/

Gentlemen please read.

To everyone who\'s expressed interest on the CLR. Rotors.
The following is a bit of history, background, development, and advantages of the product.

These Rotors are a result of years of R&D on both Hi-output Turbocharged and NA. Rotary engines.

Originally intended for ITA competition, an idea to gain port timing was developed.
Once proven, it quickly found it\'s way into and adopted by certain SCCA
E-Prod. & GT-3 National Champions.


CLR\'s development and applications of this technology dates back to 1988\'

Now that Mazda has applied this tech. to the Rx8 for the same basic porpose, suddenly the "CAT WAS LET OUT OF THE BAG" .
We were forced to go public with information about this tech.
Reputable engine builders have reported averages of 25 Hp. gains on NA. Side port engines

Our first attempt with "Rotor Port Phazing" on Turbo engines came in 94\'.
We saw a tremendous increase in performance, especially when conbined with properly sized Turbos & Injectors.
Further testing PROVED, radical increases in VE. at higher engine speeds.

The Rotor pictured above, resulted from a request to develop a "Reliable", daily driven, 600 BHp. Street engine to run on Pump Gas.
The outcome neted several street cars runing excess of 22 Psi. Boost, and well over
500 RWHp., ON PUMP GAS, for years on end !
All who have tryed these Rotors w/ Turbos have reported massive power gains over their previous engine setups.

Within the last few years, 3 of the top 4 Rotary Drag Racers in the country have broken many a record runing these Rotors.
One went on to win the NHRA Outlaw RWD. National Chanpionship.

Advantages of the product are:

a) A thicker, more stable & durable casting, cloned to REW. weight.
Staticly balanced to the gram, and Dynamicly balanced to work w/ REW.
Counter weights.
b) Clearenced for sustained Hi-Rpm operation.
c) Rotor port phazing, otherwise known as "scalops" allow for earlier and longer
Intake port timing duration.
The "scalops" open the Intake port, while the Rotor is physically on an
otherwise MUCH LATER crank angle. Effectivly blooking the exhaust port by the
Rotor\'s flanks, adjesent to the chamber. Thereby significantly reducing Exhaust
cross flow contamination into the Intake cycle, due to backpresure.
Delivering lower EGT\'s, & Charge Air Temps. which yeild a dencer charge.
d) Last, a Lower Compression ratio, tolerates much higher Boost levels and
further supresses heat and presure induced Detonation or Pre-ignition.

There are those who will argue that lower compression yeilds a "softer" bottom end and throttle responce,...........
Not the case, these are TUNING ISSUES that can be "Maped out" with proper understanding of what a low comp. engine requires while off boost.
With today\'s readily available EMS\'s. and tunig capabilities, that\'s no longer a valid point.
On the flip side of that argument, a single Pound of more boost, will MORE THAN make up for any lack of bottom end. Add in the the benefit of running MORE Boost, MORE often, for MORE sustained periods of time. Most will agree, their is NO argument.

The "Scalop Rotor" modifications is only effective on Side port engines.
And offer absolutly NO ADVANTAGE on full Peripheral Port configurations.

Where did the talk of porting go?

All i see is talk of rotors and compression ratios. Surely this isn\'t affected by porting?

Also, i dont really see how this thread can be of use to anyone due to the huge amount of jibberish.

If your an engineer, then thats cool, but if your aim was to get people interested in your business who are new to the rotary scene then surely you should register ad a trader and have your own section on the forum like Carl has for questions/advertising.

I\'m more confused now than I was before reading page 1.

Also is this a video of your expertise

Liam, good find! Made my evening! If Rice Racing driving is as good as his porting techniques, I wouldnt be touching him with a bargepole...

[Grant Monkhouse]

You do realise that Rice is all the way over in australia right?? As with many threads they tend to go off at a tangent at times.
