Here's the set-up. In a 92 CX
Chipped P28 8500 redline 5500 x over
B18A bottom end
B16A head GSR cams adn AEM gears
S1 B18A LS tranny..

I got a new dizzy today and put it on thinking that would fix it..No more ghetto LS on the Vtec head.

I was thinking too much advance? The intake cam is advanced about 2-3 degrees. While I still have not fine timed the ign timing with a light. Could this be my problem. The car pulls great up to about 6800-7K then I feel like I am pushing it too hard and it stops pulling. (oh yeah and i know that it is not good to be pushing the LS bottom end like this)

 

Ever thought about it being the actual ecu?

*edit*

Hell no do not rev that motor past 8,000 unless you dont want to keep it intact.

 

yea I know I know...I just wish i could take it up to 8K....
I had a P72 for a while and traded it for the p28...better X over timing.

 

any other suggestions?

 

Step on the gas harder!! -

JK - TPS?

 

id be scared to go too far... i think its good u cant go past 7, or ud prolly end up with some hurting... in your pocket that is!

 

if that bottom end isnt built and your poor like me..i woulndt take it past 7 either....

The cheese can only be put so far in front of the mouse.

 

my brother's build is about the same.. he had a b16a head on for a while with a p72 ecu.. we revved it over 7500 couple times but there's hardly any noticeable gains after that.. now it runs a b18C1 head with a b18a block, type r cams/gears.. we still don't run it over 7500 even though the ecu redlines at 8200.. xover for VTEC is at about 5200. and it's not even chipped.

um the rod ratio of a B18A/B is almost identical to that of a B18C1
B18A rod length is 137mm and the B18C is 138mm

the reason the B18A/B had a lack of a red line was not because of rod ratio, but the engines cam profiles were designed for lower rpm powerband

 

I take my SI to 8,500 everyday.

Yes i know, the fuel cut-of is like 8,200.

But for some reason my rev. limiter kicks in at 8,500 and i feel the power till than.

 

even if your power starts to drop off at a certain point it is good to shift a couple hundred rpms after that so when you get into the next gear you stay in your powerband...espescially on hondas with vtec...dropping out of vtec slows you down.
