Today I heard my new engine in VTEC for the first time and what a nice feeling that was. Me and a few friends had rent a mobile dyno to tune all day. We made a pretty good map for it but there is still some more tuning to be seen. A/F is around 12.9:1. Even though it made 230 whp and 203.8 Nm = 151 lbs/tq on 215/40-16" tires.

It might have put even more out but we did want to go over 9400 RPM. All day long it made this strange drop right after it peaked so I don't know if the tires spin or it's a software problem. But damn this **** pulls like there is no tomorrow....

where did you find to rent a portable dyno at? and how much did it run you?

 

Damn those are some nice #'s, awsome build

 

Well I live in Denmark so I don't know if you can rent one in the US.

 

mods list please, if you dont mind.

BTW great freaking numbers

 

B20B3 block with JITA sleeves bored to 84.5 mm.
IB Spec Wiseco 3.6 cc dome pistons
Probe Ultra Light rods
RPM Service 72 mm. TB
JG Sheetmetal IM
3" CAI with 6" velocity stack
RLZ Stage3 B16A2 head
IB Spec cams
IB Spec valvetrain
IB Spec exhaust valves
Omni intake valves
SMSP B20VTEC header
3" Carsound cat
3" Thermal cat back
Hondata S200

Compression around 12.3:1

 

wow! thats extremely inpressive!! congrats.... video?

 

Glad you got it back together did you end up using that bin file as a base?

 

Not too shabby
Glad you got it up and running again after cracking the sleeves.

 

giid HP but i think the TQ is alittle low, in my 84mm bore with 89mm stroke i had 160 ft tq and that was only a base tune so far with 11.1 cr

i bet u have rmf header they seem to get free 10lbs tq

 

yes sir, randy is the ****

and my tuner may have had somethign to do with it (jeff evans)

that and the head work (headgames motorworks)

 

HELL YEA MAN , great numbers. Get a video ASAP!!!

 

Yes video...good long video...sick car.

Must be why his headers seem to make cars faster, even if they happen to LOSE power. The dyno doesn't always tell the whole story guys. The true test is whether it is faster on the track. Which is why Randy's headers are on some of the fastest cars in the world.

 

congrats on the nice result yes it was a very good day and some damn good numbers we pulled out of it.
Tbone: I used Todd's (b19coupe) bin as a base .But had to modify it quite a bit. It's not perfectly tuned yet,but we ran out of time.

 

Damn those b20vtec's have been impressing me lately. 230whp = DAMN.
This is cool especially since you're over in denmark.

 

Here are two vids from last night... I will try and get some street action today

DAM! looks & sounds great!. Congrats!

 

you can't really compare dyno figures like that, particularly between different makes and models of dynos. don't forget that gearing will dramatically change the torque reading too.

Are you refering to the 0.973 number? No it's just a correction factor. A/F was around 12.9:1 under WOT.

yah it makes sense. just because a certain part makes a higher peak number, doesnt mean it will get you down the track faster.

 

Nice. I see the charactistic huge torque hump Brad is always tells me about with his heads.
