Reving past the limiter


Toua

Recommended Posts

Since the Esprit redlines around 7200rpms.. is there a chip to rev past that safely. For my Honda there is a chip like that. I rev my engine all the way to 9000rpms!.. just wondering about it. Does anyone ever modify their car to past the 7000rpm limit?

Forget Joy, where's that hunk :lol:

seriously. Why would you want to do that, barring other serious modifications? I think the rev limit is set stock on the Esprit for a reason... Though probably the guys with the racing Esprits can chime in. But I don't think there's a need to on a street car :lol: power aplenty at 7000

MJ is a bastard. He stopped calling me on my twelfth birthday. (intimidated cause my c*ck was bigger)

Remember. I'm not a monster like MJ. At least I like girls :lol:

Jesus this could turn rude... Moderator buttons at the ready guys!!!

:lol:

Back on topic...

To be honest, my car has gone past it's usefulness when i hit the rev limiter.

I'm told the limiter kills the spark but not the fuel, so i'm interested to see if

my decatted and de-silenced exhaust flashes more fire than usual when i hit

the limiter. Just need some long windows and the right road.

:lol:

so are you saying that at near rev limit or pass it on a STOCK esprit it will shoot flames out of the tailpipe?

Dunno, maybe? What i meant by more than 'usual', is more than usual

on mine since i've had the silencer and cat removed. With the cat and

silencer in place, it did not have such nice overun but you still got the

odd flash.

I think any Turbo car, even/especially perfectly tuned, can produce fire from

the tailpipe under some circumstances? (eg lifting off after hard full throttle?).

I am however not a tech guy, and i suppose an excessive pursuit of flames

out the exhaust will be possible due to both good and badly set up cars.

? :lol:

I'll ignore the photos and try to answer your question seriously. Cars prior to the SE's had cast iron tappets which can break if revved above 7000 rpms. Cracked iron tappets are common.

Power will fall off as well if stock 107 cams are retained, meaning there's little point in revving a stock motor any higher. If you want to spin the motor higher, you'll need steel tappets.

I'd recommend thin wall lightweight tappets and special valve springs both available from QED. I'd also recommend an intake camshaft change, to either Garry Kemp's high lift intake cam, a QED 420, or the stock 272 degree duration intake cam from a 912 N/A motor.

With the QED 420 intake and 104 lobe centers peak power will come at 7200, falling off gently thereafter. There's not much point to revving the motor over 7600 rpm, unless in the middle of a corner, when shifting may be inconvenient and could upset the balance of the chassis.

Changing the cam timing can push peak power 500 rpm higher, at the expense of low end torque and slower turbo spool up. While perhaps a good idea for a LeMans racer, I wouldn't advise it for a road car.

flames in the exhaust comes from removing the catalyst.

the catalyst reduces VOCs and NOxs

by thermal oxidation at a lower temp than without it.

these volatile organic compounds are--you guessed it--volatile (flammable)

and ignite somewhere in the exhaust system.

high revs just push it out faster and so you see flames

comminig out of the tail pipe.

any engine does this
