What are the best shift points?

[240dreams]

I searched.

[Onizuka]

What ever your redline is, then just modulate the throttle depending on how much traction you want.

[240dreams]

so take it to 7.5lk? it doesn't seem too safe. i heard that shifting around 6k is more efficient?

[Onizuka]

Last time I check the SR's redline is 7000rpms, maybe 7200. Shifting a 6000rpm is for guys with NA KA's.

Cars have a redline for a reason, the motor is SAFE to be reved up to that point as determined by Nissan. I would recomend rocker arm stoppers regardless if you explore the redline or not.

7500 is redline 7600 is gov point...yer shifting point depends on yer turbo..the T25 sucks for boost past 5500-6000 rpms...it doesnt hold boost very well cause its so small...now when u upgrade the turbo to something bigger ur top end will increase

[Red_Liner]

yeah, u're just losing time if u shift past a certain point with a tiny turbo....

[ItzGenX]

My redline is at 7800 stock. I shift at 7.5 if I am going somewhere fast. Shifting at 7.5 got me the time in my sig, so I do not see anything wrong with it. There is a power loss that can be felt at after 6k though, but it is not enough to shift to the next gear and actually pick up slower since the next gear is shorter. I've actually tried experimenting at the track and shifting at 6.5 or 7 and my times were around 13.7 or 13.8 with a 2.0 and a 2.1 60ft.

I'm sure you meant longer.

I shift out of First at 7.2 or so, then 2nd to 3rd usually about 7k, then 7k from then on. The T25 really does not put out much power past 7k. 6k is a bit low I think. But whatever floats your boat, it will also depend on your other mods. Shift points are different for every car unless they have the exact same mods. You really have to figure it out for yourself.

[Onizuka]

You guys are right, Redline is 7.5K. Its safe to rev to that, but I recomend rocker arm stoppers if your going to be bounching off the rev limiter alot.

[dj_lennon_franz]

will it hurt the engine to bounce the limiter...i try not to do this alot while drifting as i know its not good to do without rocker arm stoppers...but i mean even with them on will it drastically mess with the motor???

[Onizuka]

If a rocker arm comes off or breaks all that happens is that the 2 valves it controls will stay shut and the cam could possibly get scarred. One rocker arm probably costs more than rocker arm stoppers so why not just invest in them anyways.

[240dreams]

good points

[240SXer]

I've got rocker arm stoppers. If I didnt I wouldnt go past 7k, i've miss shifted before and without the stoppers there is a good chance i'd be shopping for a new motor.

[MainEvent212]

i've never mis shifted w/ my SR...but i'm looking for rocker arm stopers cuz i like to stay between 6-7k when i'm making the rear tires dance

[SRdave240]

My best times (13.8@100mph) are had when I wrap it out in first and shift at about 6500 in the rest of the gears. You can figure your perfect shift points if you have your car dyno'd.

Is it me, or is there a lot of misinformation floating around here lately. It doesn't make any sense that Nissan would build an engine that you couldn't hit the revlimiter on. If rocker arm stoppers were required in order to rev to the limiter, don't you think they'd make the limiter lower? Now if you're an idiot and you constantly ride the rev limiter, then you're just asking for it.

[240SXer]

Humm... Maybe when you get your SR you'll notice how much money you spent, and you'll notice how much you dont' want it broken just because you can't stay away from revving it too high. The rocker arm stoppers aren't only for just reving it high, if you miss shift (4th to 3rd or somthing like that) without rocker arm stoppers there is a good chance you'll destory the motor. It happens all the time in high revving cars (RSX, Celica, etc.). Believe it or not but engines aren't really made from the factory to take the amount of abuse a real racer is going to give it.

[RobDET]

with the crappy stock motor mounts its VERY easy to do a 1-2-3-2 shift instead of a 1-2-3-4 shift... It's scarry as hell. I've done it about 3 times with no issues so far. I have no RAS and have seen Revvs significantly higher than the revv limiter without problems. It usually stays abov 7.5 for about half a second when you miss a shift like that...

[f150intally]

I wind mine to 7500 in every gear and run 13.5 @ 104.25.

[240SXer]

At what boost? What turbo?

ditto

I shift at 7k I havn't gone to the track enough to get past the KA24 7000 RPM redline tach.

1 BAR, stock turbo. Below is a link to my list of mods:

sorry for being offtopic, but f150 do you have a sound clip of your exhaust, i bought the Blitz muffler to put onto my 240z with my redtop SR and i hear how it sounds???

nissan made the motor to be sporty yes...but they didnt build it to endure the type of driving that people like you and i put on the motor...sure nissan knew that there were going to be people racing the motor but the average person who guys a silvia in japan europe or australia doesnt buy it to beat the **** out of it...they buy it to have as a fun and sporty car...the average person doesnt rev the piss out of the motor either on a day to day basis...so rocker arm stoppers werent needed as nissan was making this car and motor for the GENERAL PUBLIC not the minority who race them...they knew if u raced the motor u would upgrade it with parts that are meant for racing which includes adding rocker arm stoppers...see where my point is going???

No,

I don't but i can get one if you want it. That is something a lot of people want but I haven't provided. Now that I have a camcorder I should be able to get it.

I mean yes, went outside and recorded it with my laptop. You should really have a subwoofer to get the full effect.

PLEASE RIGHT CLICK AND SAVE AS

EDIT: Oh yeah, that is with the silencer in!

[SR 240Z]

thats awesome now, sorry if im a pain in the butt but can u do one with silencer out or if its too much of a hassle no worries, this helps either way...

Yes, I will get one with the silencer out. I was going to do this yesterday but my exhaust was too hot from the ride home. I'll do it tonight when it cools down.

[Zadok]

Forgive me, dumb question about Rocker Arm Stoppers!How hard\whats involved in installing RAS in a Redtop.And why is the Greddy RAS so much cheaper?
