Thread: N1s

Only bolton not there is a pop charger, exhaust is eBay header and 3inch exhaust. I guess a dyno will be next.


And I'm switching over at 5200rpm

Sounds too low but the dyno will tell you where u should be switching at.

where are you revving to and what cams were in the car before, i switched @ 5.5k, 5.2 felt smooth but it started surging forward at 6k upwards, also if your mapped for stock cams, the car wont feel stronger as your moving more air into the engine so you needto match it with fuel,

calum says to remove timing with n1's...

i didnt feel a thing untill it was tuned...

hey i kno u put those cams in for u!! lol

^This should be the case.

^I know I noticed this when I put in my BC2's in over my stock cams for my DE. Top end was waaaay different. I don't see why it wouldn't be the same for a VE unless he didn't mark his timing.

Ya Iv known him since waaaaay back in the day...


Maybe the power is there and I'm just not feeling it, I need to jump on a dyno

So I was thinking, my ECU setup is a CalumBasic with a JWT tune, and it prob is timing that is off depending on what JWT has the program....

Otherwise I'm doing a full tune just to cover that ground....

That's always the answer ^ and again, from what Calum has said... the bigger the cam the more timing you should remove after peak torque... if your tune is set for stock cams you probably have too much timing after the cam switch.

"So for example we found that a stock VE cam likes 36 degrees timing up top, but a SR16VE doesn't make any more power beyond 30 degrees."

"...you advance the timing after peak torque. The trick is how much you have to advance it. This is one of the biggest misconceptions- 'more timing = more power'. Your eyes open (at least mine did) the first time you see that this is dead wrong on a dyno."

"Having your timing curve work with you cam switching is something that has to be done on the dyno, but having those two work together gets you what you see in his dyno runs- a much fatter curve."

Aka... you would benefit most if you retuned and adjusted your cams switch point.
