I believe a 14000 RPM can be reached, but I don't believe in a 12A or a 13B. That number just seems too high, even if someone dropped a massive shot of NOS into the engine.

I will tell you now, unless he race clearanced your rotors, your engine will very likley disassemble itself very soon if you keep that up.
That is the most ridiculous thing I have herd in a while bro, I herd your car and it sounded like you were reving to around 8000rpm???
That rpm is plain stupid for an engine without hardened stationary gears, snap ringed rotors and proper clearances, I think you will find when it comes apart that there will be shinny spots on the rotor faces near the ends of the combustion pockets and at the tips on the sides of the rotors.
Are you sure Bill is not a leb?? lol..... That is the kind of wierd **** they get up to in Lebanon
PS I feel your engines pain..poor little engine

Launches were done at 10500rpm, I have the data logs to prove it. Gear changes were done at 8900rpm max on the same data log.
Remember the blue Datto 1200 AVENGE from Mazsport? That car had 30+ passes launching off 10500rpm and the engine was fine when it was pulled down. Craig Dyson launches off a 10000rpm limit and so do most of the other racers.
You will soon find out too if you are building a drag car. Revs+dump=low 60ft time. Low 60ft=low ET.

Our car has an auto box, so I will not need such extra stress on our engine
Oh well, that is plain crazy ****....I would never do that to an engine that has not been clearanced properly. Maybe that is why drag guys go through engines so quickly for very little actual distance covered ?
30x.4km=12km distance covered before a rebuild !
I remember pac telling me that out of a 500bhp engine you should be able to do 80 passes before it needs a rebuild...WOW thats a huge 32km !!!!
My engine has done over 200km of full power full race KM's (circuit racing since I built it running at power levels from 500bhp to 600bhp, thats 500 1/4 mile passes ! + 10 000km of street driving with alot of power testing on the road.
I will stick to normal rev limits I think !
Steve I am not having a shot at you mate, just find this stuff interesting

That Datto engine got pulled down because it cooked itself with a dud radiator cap! lol
I did 21 passes that weekend and the engine is a year old to boot having covered quick a few kms in its time, so the engine is strong and healthy mate!
If Bill tells me to do it, I will. He built the engine and knows what it can and can't do, if he says it can launched from 11000rpm, I believe him

Each to his own bro !
My name is "Bill" and I tell you to launch at 13000rpm LOL
bye bye engine..........
We have similar power so it will be interesting to see how long she lasts?

If you go to a dyno in the near future get them to log your actual rpm of the engine, take it to 11000rpm and see how little power you have. You will be suprised
The only benifit I can see in abusing the **** out of your little engine at the launch like this is because of the extra inertia with the higher engine speed.
You should simply put a "drag racing" fly wheel on the engine to get the same effect, while still using a normal rev limit that will not shorten the life of the engine.
Makes more sence to me using a heavier flywheel to get the extra inertia need for the launch.

But AVENGE told me himself and others too, you rasie your launch RPM and your times will drop. I started out at 8000rpm or so and was running 10.7s etc. Up to 10500rpm and 10.32

) I think I would need to launch at high rpm too?That makes a real big difference to your times bro !

Man i have no idea what my clutch/flywheel package weighs but its pretty light! Has more holes in it than swiss cheese!
1/4 mile times are won and lost in the first 60ft mate! **** your launch and its all over! You might run big MPH but thats about it...though a 12.0 @ 133mph would be pretty funny!

I may just take it out one night (creek) to see what mph it will run, I know you loos a bit through the slow launch in your final mph, but it still should be high?

Alot of people are of the opinion that you might fudge a launch, but your car (if it has it in it) will run big MPH. Get a perfect launch and your MPH will be down.
Its rare you get both goot 60ft AND good MPH, though all weekend my best MPH was 133, even though I dropped half a second on ET
Ah drag racing, gotta love it

I did 118mph but with the dodgy boost solenoid that wouldn't hold boost. And street tyres too!
Im planning to take it back out again in street mode and have a crack at a low 11 at low/mid 120mph....

We should have ago together? ...I will need to organise a car trailer and a vehicle as there would be a great chance of me breaking something...but it sounds like it would be fun?
**** it if I do not sell my car, I will try to get up there

What kind of motor and set up do you run? I was just wondering cus you jumped in and i am not familiar with what your running. Oh ya i have a flywheel exactly like yours. I weighted mine and it was around 12lbs. without balancer.

Rice - Yeah for sure! You should come up and race at Supernats on September 13!

Custom Plazmaman aluminium intercooler (Core is 48cm high, 38cm wide and 9cm deep)
Standard RX7 radiator. (58cm high, 54cm wide and 5cm deep)
Haltech E6K running boost contoller and firing S4/5 coil packs tuned by HITman.
2 x 550cc primary injectors and 2 x 1650cc Bosch secondary injectors.
3 inch exhaust sytem off turbo, hi flow cat with straight through resonator and custom muffler.
Twin plate RE Amemiya clutch and lightened flywheel.
T2 box with custom quick shift.
Borg warner (10 bolt chevy?) diff 31 spline billet axles, 4.10 LSD centre and 3.5 inch diff.
FR17 Simmons front and back; 17x7 front and 17x8 rear with Yokohama A032R 225/45/17 tyres on the back.
Koni adjustable shocks front and back riding on lowered Kings springs.
Modified pick up on fuel tank feeding a low pressure Carter pump which feeds a 3 litre surge tank. Fuel then sent forward by 2 Bosch Motorsport 5L/minute pumps.
Max power on pump fuel approx 500rwhp (433rwhp on Dyno Dynamics dyno which read ~15% less than Dynojet)
Max power on C16 560rwhp (472rwhp on DTS dyno, again read less than dynojet) on 26psi.
Best ET - Pump fuel and street tyres is 11.8 @ 118mph
Best ET - Race fuel and slicks is a 10.32 @ 133mph

Does this guy happen to have an SA model? The '79-80 model, the one with the combination tach and voltmeter... see where I'm getting? 7000 or so RPM points to 14 on the inner ring of numbers.
I know MY 12A didn't like going over 8500 for a couple seconds...
Don't try THIS at home boys and girls...

I'll admit, that i never did have the 12a dyno'd. I should have. Shoot..i wish i could of even taken it to the track. But i did have the Inj 13B dyno'd.
Also, i never said that the motor "Did'nt like to go below 11k" I just said it was still pulling at 11k rpms.
CJG- Hopefully you can come down to one of the battle of the import runs at Woodburn. I'll see if i can get you a pass with either my buddy Paul who runs the 13B peripheral, or Chris...or maybe it might be better to contact Blake up in seattle. He probably would give you a ride. Shoot, you could call Bill Burnham
(Auto world, or the guy that use to have the 3 rotor), and ask him where he shifts his peripheral port engine.
Rice- Why would I lie, about a motor making power to 11k rpms? If i was lieing all it would do is hurt Robs, and my reputation. Rob is'nt some backyard tuner, who makes his peripheral port housings using a drill press you know. Shoot, i don't think its so unbelievable. The first time on the dyno my n/a 90 Rx-7 made peak power at 8k rpms. On anouther motor i had, (street port 13B, na too.) It made peak power at around 8,250-8400. I wish i had a scanner, then i could show everyone. Let me check around...i might have some pictures of the motors them selves though.
