I think at 5500 Thor keeps the vvl activated between shifts cause his ecu revs to 8000rpm.

I see what you are saying with the stock sr20ve cams, but with Sr16ve cams the cam switch at 5100 is ok though?

Well that's where I made best use of the power band when we dynoed anyways.

Yeah, that is fine for sr16 cams. Some would say it is low, but if you made best power on the dyno then stick with it. I don't have a rev limiter but there is no need to rev to 8k on stock cams especially wiht stock valve springs.

You hear that Thor. You could rev lil more you still wont be getting any more power up there. Beware of the cammed DEs that live between 6000 and 8500 rpm.

yeah id say low to mid 14's is easily doable. my buddies has some weight taken out of it and he has a de/ve hybrid with franklin stage 3's (n1 copies basicly) and his b14 should easily be in the high 13's with good traction. My buddies nx that runs 13.0 just pulls him topend but he stays fairly close. But yeah there is no reason for you not to hit at aleast a low to mid 14.

Oh and yeah activate those cams much earlier. When i had my stock cam ve i had them hit at 4600 and it hit hard and pulled all the way from there to 8k rpms. Hell my buddy with the b14 now has my msd box and he activates his at the same 4600 and again it pulls quite well its a noticable gain when it hits even that early. He also has cam gears on them at +2.5,-2.5 to help move the powerband down a bit. He can still rev it out to 9k easily in first and second. Again there is headwork done as well.

Ok.

I dont think he revs that high on a daily basis but I guess if your vvl is at 5500 and you want to stay in high cams when you shift, then you may have to rev to 8000rpm.

i gats the greddy mss so i can make the cams come in at say 5k and not fall off at all even if its a 1k..... its flexible like that...... will be moving it down a bit to 5 k and see what happens..... wont kno till i dyno but well see what happens.....cam in a de is fine till i get the n1 so this is my weakest point...take advantage if u can....till the end of the world for u DEers

check this, my friend's 20ve 200sx ser hit a 14.3 with slicks. IIRC he had a 2.01 60ft and maybe 95+mph trap speed. the only mods he has is mss 4700RPM I/E, SAFC2, g20 ECU (7500RPM redline), DE 259cc injectors, stock cams, fuji header, headlight intake, 2.25" test pipe, rear seats removed, and no rear section exhaust but still using stock size mid-pipe! pretty good time IMO.

ok so i was idle last nite and decided to stop at a gas station and try to remember how to move the points with the mss...been a while..... so i got it to 5200 rpm and there was a difference with the response....bump it down to 5000 rpm this morning and the same again....ill be leaving it there ontil dyno time but the car feels different and for me that must mean something cause i never even feel the difference with the liten flywheel..... car gets to vvl faster and pulls just ask hard.....should mean that i have a better mid range then......
