With a b18a1 should you shift at 7? or should you shift at 6300 because acura says that 6300 is at its most power at 140hp?? so why go past 6300 then?? any help?

Shift when you stop making power ...

I always shifted at 7 on the dot,took me a while to stop hiting the rev limited tho

um ok a stock b18a1 has a redline of 6750. b18b has the redline at roughly 7k

no shit buddy im pretty sure when people shift they at least go to the 7. i know what red line ends at but i wanted to know when the best time to shift was. either at 6300, 6800 or at 7.

I use to shift my B20Z2 at 7700

bye bye B20

It took about a year but I think it was more my fault. I knew it burned oil and I took it out one day and now it has a slight knock at high rpms. That's good though, now I can add ARP rod and head bolts and raise the compression when I have it rebuilt.

You go past to get the most power under the curve... you want to go slightly past the power peak in most cases so that your upshift falls right back to just before the power peak. Look at a power graph and see how many rpms you're going to use in each gear, then look and see what the best way is to stay at the highest average power level through the WHOLE gear. For most engines, you'll shift AFTER the power peak.

You have to ge the car dyno'd to see where you stop making power. but go a tad past the drop off point and shift, that way you will be able to keep it up in the next gear. With a stock ls on a b18a you should probably shift around 6300-6400. With a b18b and cams i only made power to 6800 so with ur engine stock shift around 6400 or so.

what i dont get is how a stock b18a1 is revving to 7k. with out some kind of ecu work to remove the fuel cut off. or rev limiter.. and if you didnt have the work done to let it rev to 7k. then the last owner did and id be kinda leary of that motor.

Moved to appropriate forum... also modified title to direct attention appropriately. I thought this thread was related to Red Line Lubricants...

I granny shift and double clutch like I should.

I tryed shifting at 6400 and noticed a little more pull back in the seat (could be all in my mind) but I tryed it. I was wondering with all you non vtec guys what do you do? Shift at 6400 or red line?

6500

I'll try 6500. Thanks

I usually bounce 1st off the rev limiter, second @7100, 3rd @7000 and have never maxed out 4th LOL. HOWEVER, when I was NA I shifted her at about 6700. Beyond that I just felt like I was reving for no reason.

hahaha I have maxed out 4th. Its not very impressive on a basically stock ls

i used to have a DA and just kept redlining the motor and my rings went bad didn't hold compression and burnt oil real bad about a quart every 2 days so i learned my mistake. now i got a 94 RS and 1st gear i take it to 7500, 2nd 7500, 3rd 7000, and 4th 6500

EJ1 w/b18b ITR tranny w/LSD
Drag racing I shift at 6500....
Autocrossing I shift at 7800....

i would say in first go up to redline then the rest of the gears shift at 6600 or so maybe less even.

oh i shift at say 8300 in my b20 if im tryin
