How would you prolong the life of your rotary ?

[Grizzly]

Just out of curiosity, say you were pushing around 500Bhp, what would you do to make sure the wee rotary doesn\'t need a visit to the rebuilders every 6 months or year ?
:driving

Don\'t drive it, Just look at it and Polish it just for god sake don\'t drive it.... LOL

Only Joking, I\'d have to agree with the Lower boost theory, if you have it set up foir 500hp does\'nt mean you have to run that all the time. Plus to make a Rotary last takes Lots of TLC and Respect for the car.

nope, i wouldnt build them for others if you paid me!   I couldnt think of anything worse than being a Rotary engine builder/tuner for a living.  Your customers are never going to be satisfied for long!

oh please...

[iaint]

Not compared to a early TVR ajp lump!

that was until they realeased the Speed 6 which eclipsed the AJP by a country mile!!!

[ashc]

Rebuilt It!


2 hours to take it out,
2 hours to strip it,
2 hours to clean it,
2 hours to re assemble,
2 hours to fit accessories
2 hours to refit to car!
Job done

next time can i watch?! :yes

[antnicuk]

your too late, i\'m almost done,  
BTW plus if you want porting add a day, its an awful job!

i agree they are sensitive engines but i dont think delicate is the right word as when they are set up right they really can last well considering the power. I did seriously look into using a different engine but decided against it on a purely cost basis.  For me everything else is more expensive but i would definately back anyone doing a V8 conversion.

If the water temps are good, the intake temps are good, the tune is safe and you rung w/i and premix they will run long and hard. Where you encounter problems is when one of the above is slightly out the chances it will fail whereas another power plant might survive.

I\'m no rotary fanatic, far from it but they work for me and they are what i know.

[D1 WTF]

got to be the most fragile performance lump ever

nah 7k miles and 4 months on two engines is good i think :rolleyes:   lets see how long the 3rd engine will last

[ashc]

should a normal stock car last longer with premix then?

[TonyC]

If you are running an engine that is producing twice it\'s original power you have to face up to the fact that it will need frequeent maintenance. \'aint no way around it.
My old 4 cylinder race engine would be refreshed evey season - that is only around 300-400 miles! if it wasn\'t it would be much more likley to fail the following season.

Power costs. The End.

Hmm, not exactly what i wanted to hear
rebuild rebuild rebuild

[BlitzBoy]

Just under 4K hard driven miles on the HB and going strong (Premis baby ), record for me, 1st engine I done when OMP failed on the rear rotor was only 2K miles, the second one I done was warping the seals on the front rotor not enough lube at high boost that was 2K miles as well again OMP is cr%p for high HP.

So premix is working well for me at the mo now with added AQ WI , I think next time I blow it Im gonna have a go at it myself in terms of rebuild get Era to teach me. But I have a feeling that wont be for another 10K miles at least

12k on 500 as a daily. OMP no premix or water injection running at 1.1 bar. Gets ragged as often as traffic conditions allow. Was going pre mix but Pip more or less talked me out of it. Finding some wood to touch right now.

12k on 500 as a daily. OMP no premix or water injection running at 1.1 bar. Gets ragged as often as possible which lets face it is only a small percentage of road driving. Was going pre mix but Pip more or less talked me out of it. Finding some wood to touch right now.

Hmmm clicked quote not edit.

[darko32]

sorry to be ignorant but what does premix mean??

[BlitzBoy]

adding 2-stroke oil to the petrol on fill up at a ratio of 100:1 to 200:1 depending if you have the OMP still installed or not
