thanks to Don F , for your Weber venturi setup sugestion

 

so your vtec is locked to the big lobe?

 

261 Flywheel HP with a 15% drivetrain loss is about 221whp... Good job on the build...

Any pics of the header?

How much power did it have when it ran 13.5 on street tires?

no, i engage the vtec solenoid signal to the autometer shift light cable (engage @ 5000)

the WHP was 230ish, im forgot the exact number, i didnt printed it, but i have it photoed , latter i'll posted here with the header pict also.
i never dynoed it when 13.5 with street tyres. but i assumed it arround 250hp

 

how did you tune the fuel at the from small lobe to big lobe....im under the impression that carbs cant automatically adjust fuel curves....

unless your running rich at low rpms...

I always thought that weber carbs were much like motorcycle carbs that have an idle jet, low throttle jet, and a high throttle jet. something like that, its been a while since I messed with motorcycles.

I hate that people up compression and claim stock block. I know there are other gains to be made in the block besides pistons/compression, but dammit if that's not the first thing you think of.

milling the head...has nothing to do with stock block.

I understand that, it wasn't a statement of fact, it was one of opinion.

 

Wow, very nice numbers guy!

 

nice #'s. witing to see pics of header. also, who did the head porting if u dont mind me asking,

 

subscribed for pics of carb and header

 

nice numbers, but you should really bump your vtec crossover higher. It will get rid of that dip.

yesss... very2 RICH at low RPM.. the afr under 7000 was 11:1 ish.
but i dont give a damn about under 5000rpm power, since i didnt drive it every day.

DarkKnight1 &lt;--- dont hate me dude , oh yeah, so im wrong about the CR. because 1st i thought 11.8:1 was the stock jdm itr CR.. sorry

 

98vtec &lt;--- yes, i would try 6300-6500 cross over. thanks

btw guys, this header acctually wasnt design for 1.8L, i was for 2.0 L, for the next block for this motor.
