Thread: The Truth about the SR20VET Exhaust camshaft.

I have been testing the VET exhaust cam this week, to be fair i did not try leaving it on low lobe, was switching to high lobe at 5100rpm. Compared to the P11 cam i was running, it seems to hit full boost about 500 rpm sooner, and it revs cleanly to 8k, whereas the P11 cam would fall over around 6500.

Specs are, W11 bottom end, 16ve head, p11 intake cam, n1 intake, tubular manifold, 2871r, 38mm w/g, 3" exhaust.

Need to do more testing, and prob get it on the dyno. I had to add massive amounts of fuel as it came onto boost to stop it leaning out since it seems to hit so hard now.

Damn soo 500rpm earlier spool and 1500rpm extra power band........sounds like a winner.

This was with the sr20ve intake cam or 16ve intake?

I think I need to get my vet cams back off someone I lent to on this forum

Did you dyno with the old cams? Would be nice to compare old / new dyno between the cams for sure. I'm going to dyno with the P11 ve cams and might switch to P12 or VET cams later myself.

p11 sr20ve intake cam atm.

Havent had a chance to get it on the dyno, the massive amounts of extra fuel required around 3 to 4500 as it came on boost would stand by the butt dyno that its making more power, and extra fuel over 7k.

Ive had some many issues with my Nemu trying to get the car to run right, so i dont want to waste money on the dyno until i work out why its such a pig to drive at low speeds and has the worst idle ever on a car, its a total embarrassment to drive. Also i had a theft last week and had all my keys and alarm remotes stolen, so the car is parked up until i can stand the sight of it again. If i get around to it again one day i will try get another dyno run done of the current setup vs previous, as the vet ex cam is the only major change.

I'm running vet cams straight up. 60 trim garret and sidewinder manifold. My butt dyno tells me the car made power especially beyond 5krpm and makes bost at about 3700rpm. Was able to pull away from my friends' z06 corvett on a high way roll on 15psi.

What ECU?

Even on a non log manifold (GTiR one) I made a lot more power at 14psi with VET cams. The more psi you run the more they shine, at under 10psi it's kind of a wash though, so not worth shelling out the extra cash on them.

how does the VET cam work at low rpm compared to stock VE cams? and loss on the bottom end with these?

Not sure what your trying to ask?

What do you mean how does it work?

What do you mean loss on the bottom end?
