THis is my friend's car, and we just confused,,,, The name of owner is JT-sport.
Why with 311whp, My friend's just passed 12.4 second...
Even he ran @ crappy track.. I think this is very bad Passed time,

We race @ regular circuit... not @ drag strip.

This is the car...








Less than 900kg for the weight

So, I think this car run bad.. How to get better??
and, how if 311whp run @ drag strip like englishtown, cayuga, Etc...
Can this car passed mid10sec or may be 11sec??

 

TIM GREY's passed 10 second with 303whp...

 

Whats the trap speed looking like? Do you guys have 60 foot markers over there?

 

My guess is that because this is a circuit and not a drag strip the launch surface sucks...which will lead to poor 60ft times. Having a good 60ft time makes a HUGE difference to your overall ET. What was his 60ft?

 

dyno corrections could be messed up, making it read way high

 

Yes there is something wrong.........what suspension do you have???whats your 60 foot?

 

try again on drag strip... and maybe try another driver? did 12.4 was is best ET or he just did one? it could be lot of things...

 

I think this is very likely.

I'm not honda specialist but to me 311whp from a b20V running carbs seems to be on the high side of feasible.

Also what is the elevation and the weather conditions of the track you ran at? Running Naturally aspirated, altitude and weather can make a big difference compared to Forced Induction

 

What was the MPH?

 

yeah we need more info to give you a definite answer, too many factors

Driver Error
Track Conditions
Dyno correction
Car setup
Full Time slip

So yeah I think that covers all the bases

 

+1

 

This is the same car from a couple months ago. lol

 

Indonesian dynos tend to read higher from what I've heard.

 

If this car were at a strip it would probably dip in to the low 11s and high 10s. The trap speed of 120 mph is indicate of the power.

 

I just don't see that engine making 311whp, I'm not trying to hate but this came from the same guy with 200+whp allmotor Sohc d-series, lol, that's explain the high hp reading

 

So what you are saying is that 200whp is not possible from a D???

 

I'm not saying it's impossible to make 200whp from a D, but if you read his build up on the D then you'll know it's impossible for him to make 200whp out of his D, here's my simple D build

I can see this car make that type of power. His trap speed is 120 mph with a very bad 60 ft time.

Carbs cannot be beat for atomization especially in a pure race application.

 

yup that is why bisi ran them for so long

 

In a pure race app. like you said, will outperform just about anything. Power and tq increase dramatically.. The only thing better than carbs is the Kinsler injection. They emulate carbs though. More like "Electronic Carbs".

 

Yesss, The trap speed is 120MPH++

 

Crabs?
We don't do crabs. you would never catch them if we did. lol

 

lol... Yeah I caught that just before I left for the shop.. Fixed now. Its too bad I cant run the Kinsler setup in S/S with my little d15.. I would love to see the outcome.

 

yeah, but if atmospheric conditions change, then you need to re-jet. and if the conditions are different than the dyno room, then it's more than likely off on AFR at the track. which is why EFI has so many sensors and pesky electronics and maps.

 

You are absolutely correct... Although with a wideband o2 you can re-jet very easily at the track. EFI is much more stable from one place to another. But with carbs, its "ALL OUT" raw power. I have nothing against EFI at all.. I just like the carbs for the shear power they provide along with a very simple setup.
