only put a couple miles on this, plus all of our street tuning. but i would have to say that I LOVE THIS MOTOR. just has amazing torque. lots of 'passing power' in 5th, just lay into it and your movin quick. or maybe i have just been driving B16's and single cams too long lol


for those that have tuned similar setups with Skunk2 Pro2 cams, you have the same tq curve? kinda odd that i made more torque on low cam than high cam, and that shitty dip in the VTEC crossover area. oh yeah and VTEC wanted to be at 6400rpms i believe.

Nice job.

 

i made peak torque at 7700 or so on my pro 2s. were they degreed?

 

I just looked at the graph and could tell what header he was using. That pairing always sucks between 6 and 7. I don't understand why everyone uses those headers. Oh well decent numbers tho, should be higher with pro 2's. Needs more compression to wake the cams up. Thats what graphs on 2L's look like at 11.5:1 with Pro 2's not degreed in. If the vtec wanted to be at 6,400 that is a dead give away that it needs more compression.

Higher compression doesn't buy much on a stock head.

This is basically a stock head with a over-sized header and cams not degreed in. I think if he degreed the cams in a went with a sms/dtr header that would eliminated the dip and yield more power and torque.

not really sure what degree them in is. read about it, didnt seem to make 100% since to me. we dialed in the cam gears, wouldnt that do the same thing'ish?

beautiful, the kind of response i was looking for. well not entirely, but helpful forsure! but i expect to find some things that will need improving over time.

 

anyone see anything wrong with the cam gear settings? i sure do.

Wow, I think he had better read those instructions again.

Man, it's a good thing he has room with those pistons.

He is probably .015 from disaster. If not less.

 

You did a valve job when you put those valves in right?

 

im not too worried about the P2V issues its the V2V issues.

what have you seen with pro 2s steve? i couldnt get jack out of them until i seperated them 4 degrees. the pro 3s took 5 before i was in a comfort zone.

Some of us like to live on the edge.

 

Try lowering VTEC to around 5000

Advance the exhaust cam another 3 degrees

You should be able to reach MBT without knock on the high cam. Somewhere between 34-42deg BTDC.

Having peak torque on the low cam is not right.

I have seen 2 deg's seperation net .030 clearance with 'special vj' but on something I dont know whats been done to the seats, I wouldnt go closer than 4. 3 if I woke up on the right side of the bed.

 

so, those are those cam settings bad? im fairly new to this level of tuning of NA cars.

Some of you are engine building machines! If you bend valves, its only a week downtime for some guys.

Basically, as you move the gears further away from each other, the amount of space in between your valves @ overlap (when they are both open, I and E) increases. Conversely, the closer they are numerically on the gears, the less amount of space you have in between them. Different people use different numbers as the "bare minimum" , but with only 1 cam gear deg of seperation between the cams on those particular camshafts, you are probably asking for disaster. I think I will do a vid on the next v2v check I do so people understand just how close we are talking here.

Plus you would all get to see how studly I am.

valves where just lapped.

do not want video. i dont think i can handle how studly steve is.

marshall, what the heck is intec up to? you guys have been quiet for being starting the drag season.

 

so, you think i should crank the intake back to 2* then?

when we were tuning it he said the motor didnt like the overlap on one of the cam settings. think thats when we ended up with those numbers.

Type R valves are oversized. Start there

The video eagerly anticipated, your studlyness not so much, lol.

Not sure. I havn't been involved there for over a year now. Finishing school and doing Formula-SAE stuff.

Still building motors though

Your intake looks fine. Exhaust should be advanced first. Try 5, go further if it makes more power.

pretty sure it idled like complete **** when we advanced the exhaust more than what its at. i will call my tuner and double check.
