How High Should A Blacktop Rev?

[levin20v]

Hey i know this is a wierd question,

Do any of you know how high a Black Top should rev,

I know the Silver Top reaches 8400rpm but how high should a BT go,

I ask because i had mine on the Dyno and it barely touched 7800rpm, not to mention only managing 145 Bhp

Cheers for any help on revs or increasiong bhp,

No1 have any ideas? any1 with a blacktop out there?

Black tops should i think go to 8200,

they should be a genuine 155 on the rollers

my old silver top went to 7900-8000 i think.

are you sure shes BT what year car is it and are the throttle bodies black as well

I think my rev counter might not be accurate as it show's 8,400rpm on the redline. I think early ST's go to 7,800rpm, later ones to 8,200rpm and BT's to 8,200rpm.

fairly sure as it is a ae111

will get a pic of the dyno readout up soon, they guys says the rev counter is spot on, also i heard that the silvertop hit 8400 tho,

I've you read that on here, maybe it's me spouting crap. I thought they did as thats what my rev counter shows but after further reading, they don't.

thats a BT alright....hey why are you running through one filter?....you should of gotten rid of that big airbox long time and run individual velocity stacks, those things sound SWEEET.....ive got a ST so i have t run it through the AFM :(

[levin20v]

Yeh im running an arc airbox atm, i wanna open them up tho, gotta get me some stacks.

Would my car run with a silvertop ecu then? i will check mine 2moz, hope its not a silvertop 1, then again that would solve some problems!
