Bisi puts a lot of R&D into his cams. they WILL perform. but if you were just going to do a stg1, i would go with the Delta just because it is cheaper. either way your gains wont be amazing

i would however chose the stg2 over the 272

 

X2 I used a Delta 272 in my old rex but I have heard a lot of good things from Bisi. If I had the money I would go Bisi....Proven numbers

 

Stage 2

 

272 is greater than the level one, 272 is almost the same as the bisi level two, I have tried both in the same engine, and almost no difference, the majob thing with bisi is the valve adjustement issue that you might have with delta if they grind too far, and overall bisimoto cam is a bit more refined on all powerband and better idle, but not big difference.

 

still debating this issue in my head

im worried of using the stage 2 in my stock head for the next few months or so , and having a valve drop or a spring break.

but if the delta 272 is so close to the bisi stage 2 im assuming i should be alright since ive seen quite a few builds with the 272 on a stock head/valvetrain


i just may have to go with delta for the fact of it being cheaper, im trying to find the delta cam specs if anyone can help me out with that

 

Exospeed has some great profiles as well. I will very soon be running a exospeed stage 3.

 

True, true but exospeed don't make a stage1. For a stock head i'd guess you'd be okay if you didn't go above stock revs.

Makes it a bit pointless getting a cam then though?

If you have the cash i'd go with a bisi 1

 

I would choose the Delta last out of all of them.

Just because Delta just bases they're regrinds off base profiles...

"260"
"272"

It's a cheap modification to get a good power gain. Anways they haven't tested on dyno 300 times like bisimoto, they still have experience with engines until very earlier in the 20th century.

 

exospeed DOES make a stg1 for non-vtec motors not VTEC motors. Depends on your budget here. Bisi has way more R&D and quality control but delta is damn cheap lol.

 

"Offers a 15% improvement in power over factory, with stock-like idle, with emphasis on the 1700 to 5900 rpm range. "

from bisi's site

i dont plan on going to the stock limiter, as i rarely do now

so i figured only 6k revs i assumed the springs will handle it as i wont be revving any more than im making power
