Peripheral ports

Yep it was the clutch that kept letting go.
Managed to keep the clutch together as grant says with the hks twin but then the after killing 2 gearboxes at only .5 bar and the diff starting to sound like a can of marbles I decided I would end up spending more than I wanted to on this setup. So i moved on.
I decided to put the rx7 back to a street car and concentrate on restoring the rx3.

Brian Ellis used to run that HKS clutch as well he used to break driveline components.
I think the OS Giken clutches seem to be a better match on the FD.

Of course the standard Torsen diff will sound like marbles anything over 450 bhp they are marginal lol need a plated diff instead

It would be nice to see the dyno print for this gearbox smashing monster.

Not all cars are mapped on dynos.

I do believe Ross used to map his car on the road? Correct me if I\'m wrong. And he still has the record for fastest street legal car and the highest terminal speed?

So from what a few people have said on here about fd boxes breaking it takes something near 600+bhp, so surely that would mean the car was near that power figure??

That or steve had gear boxes made from chocolate? But I doubt that?

Power doesn´t break gearboxes, torque does. Also where is peak torque located in powerband has some impact. Usually 3rd gear is what can´t hold, if you upgrade gears then casing of tranny will literally tear apart.
You can go with any power you want at 4th gear as its direct drive.

In regards of power, most optimistic situation would give just about 500 HP at 0.5 Bar

You won\'t. You will just have to take my word for it.

Your probably right but unfortunately I never had chance to try much as it came apparent quite quickly that I would never be able to put the kind of money it demanded into it.

My whole drivetrain was completely stock so a whole lot of money was needed.

[steve garbutt]

Just to put the records straight the 1st gb was a little problematic anyway but the second was a good gb but ended up mulled.

I wonder why many other people don\'t run them? Correct me if I\'m wrong but there isn\'t any of the guys in the hks drag series running PP\'s?

Chris impey is running semi PP\'s but that doesn\'t count as a PP in my eyes.

we don\'t run them because we haven\'t pushed the bounderies of the side ports, its not all about big holes :2Rolleyes

there are many factors that can contribute to breaking of transmission components from chassis bracing to power delivery. to quote a power figure and say it will break at that point is ridiculous.

Considering that at least 6 cars in the world are running 13b engines and doing 6 second 1/4 miles it\'s clear that the boundaries of the 13b are not even remotely being got close to in this country let alone porting.

[hayden]

Did you mean to saying porting or were you comparing to 20b?!? You make it sound like these 9second cars are unported. Not sure if this were your intention. Some of the quicker ones are pp too arent they??
 
Also your statement doesnt bode well on you as a engine builder? Comes across as a bit of an own goal that does.

I like big holes though

we are all well aware of this carl.. be good to see some of your cars start doing some respectable times :3gears-rh

[lowslowandold]

wtf is going on in this thread, seems like a lot of w illy waving to me. pp as a first start on the rotary ladder, cant be serious??

carl i think if you see your 13b porting way off the pace off oldone\'s? i cant remember what your 20b motor did in that FB, that time, im sure some one will remind me.

alfred beautiful words buddy
