Vtec from hell.
 

Had some fun in my brothers integra tonight on the low-boost tune. :bowrofl:

Specs?

Cant really tell if its fast or uber-gay

Can't see the vid, but I had fun in my buddy's Integra a few years back. He'd just gotten the engine built n/a (255 bhp), and was bringing up the revs slowly in his garage, with an open SMS 4-1. When VTEC engaged, it scared us, it was that loud. It had some kind of crazy Crower cams...

It's a B16b, with forged 1.8 ls internals.

We put a bus and a half on a 06 R6 that is supposedly 'built'. He sent out a text telling people not to fuck with any black integras, haha.

Nice. Are we talking about an LS/VTEC or a genuine B16B with B18B reciprocating bits? I didn't know an LS crank would work in a B16B block.

LS/VTEC. I'm a honda noob. :jerkit:

1) No way in hell it made 255hp N/A.
2) VTEC shouldnt be set to engage when the car isnt moving.

he probly had the car off the ground to allow the wheels to spin! ;)

1) Drive out to the westside and tell Don at DFE that. Also notice this is bhp, not whp. This was done on an engine dyno at DFE. Look around his shop while you're there, lots of CSR and DSR eye candy, not to mention the insane "street" engines he builds.

We're talking about a B18C block, stroker crank, 12.5:1 Cr., P&P, etc. I understand your skepticism, but it's misplaced. If it makes you feel any better, the owner had more money than sense and blew the engine with a combination of stock fuel pump and stock radiator (IMHO), and general hooning.

2) Many things are possible in the realm of EFI tuning, including engaging VTEC at a standstill. I don't know if it was intentional or not, but his car would do it.

How fast is it compared to your car?

I envy hate engines.

looks like a monster.. im not the biggest honda guy but they are awesome cars for budget builds.. there are a few around my town that are really quick

the better a vtec engine is tuned, the less obvious the vtec engagement point will be. at least while driving, i've never heard one engage while sitting still in a garage though.

You CAN set it to do that but youre not supposed to, you have to go out of your way to set it like that in hondata/crome/uberdata/neptune/ectune/etc

When the engagement point is set correctly you dont really feel it, but with all B series VTEC engines you alwasy hear it. Even when its set right, simply because youre going from a small exhaust cam to a suddenly much larger exhaust cam.
With the D series engines you dont hear it very much because it only has VTEC on the intake side, not the exhaust

How about a 300whp NA B-series? Local shop, good guys.

My friend rode in Katman's EG back in the day. The wheels would spin when VTEC engaged. Hahah...I don't think it was tuned well.

310hp/180lb??

rpms pwn j00

thats a hell of a torque curve. respect.

yes

yes, why i said it's not as obvious, certainly not startling. it's not just the point, it's the tune up to and after the crosssover point. most people just tune the wot on the vtec engaged side. i've tuned like 30 b-d series hondas

yeah, kinda. a d-series is only a single cam so there isn't the same jump in flow like in a b-series.

It leaves my car pretty hard.

It made 420whp on low boost, he's waiting for sleeves to turn it up any more.
