Here is my setup
b20 block bored to 84.5mm
Cp 12:5:1 comp pistons
Eagle rods
Itr oil pump
Block built to my specs, rods And main journals bored to get proper bearing clearances
Stock b16 head
Skunk2 pro2 cams with GE cam gears degreed in to spec
Victor x manifold ported
70mm skunk2 throttle body
Id 1000 injectors and GE fuel rail
Big tube tri-y header
Tuned on pump e85 by Mad scientist autohouse

 

12.5:1, pro2's, e85, and only 230whp?

Seems odd. That seems more like a 93 whp number.

The very defined toque dip from 5-6.5k rpm is also pretty odd.

 

This particular dyno is very low reading

 

How does this seem odd? Dyno is just a tool they all read different

 

Look at the sharp dip/climb at 5 and 6.5k rpm. That is odd.

 

Agreed. Do you have the a/f ratios handy? That HUGE vtec dip indicates something is off as well. The hp and tq dip mimic eachother

 

What degree settings did you end up at?

 

Of course they do... HP is just a mathematical equation of torque x RPM


This is a good example of a motor that can't breathe. It looks like the VTEC lobes are too big, but it's just the stock ports choking it... this motor has another 15whp in it easy. This setup is one of the few times where you could literally see 10-20whp from a good port job. It's also why the torque just falls on it's face after 7k.

Port the head and you'll see 240+

 

seems like vtec xover could be 1000 rpm higher.

 

Guys I just posted up to share my results I never asked anyone to "fix" it for me!!! I have been doing this a long time, longer then most of you and I an well aware of what's going on with the motor

 

Relax man, we are just giving you constructive criticism. No.one said you are doing anything wrong. You have been given ways to improve the setup, thats it. 220whp from a 2L is still damn nice, but there is definitely room for improvement!

 

I am not upset, I am just not here for a fix I am here to share what I have so far, I am not a dumb kid searching for the answer on why my b20vtec did make power!!! If you must know the car starting having head gasket issues on the dyno!!!

 

You guys do know that VTEC looks to be at 6500 rpms right?

OP, really good power for a stock port head, not sure if you had a nice VJ done but that can get you a bit more power. The powerband of the high cam looks good.

 

Thanks I was happy for it being a stock port head, I have a ported head but had some issues with it and we switched heads on the dyno, I will be switching back to my ported head soon!!! Also this car was tuned open header.

 

The strange dip went away when we switched to a normal shirt ram intake but the car lost 5-10 whp over the entire powerband at thay point.

I tuned this car and I questioned the dip myself, no amount of timing, nor afr change brought it out. I do agree this car could benefit from a ported head.

 

and this head was just something I had laying on the shelf, unknown mileage & valve seat condition but came off of a running car. The customer was in a position he HAD to have a head.

 

Like stated above the dip is due to the intake, it went away with a shorter intake but lost power across the whole power and, yes I could definitely benefit from a ported head but that will come later.

 

Another instance of stock ports supporting 225+whp

 

It's a stock head with a shitty header. "Only" 230?

OP I would do a different header and retune. 3" exhaust?

 

That's like my set up in my EF. Damm nice bro

Good job. 230 is not bad at all I'm happy at my set up. I know there's more but running the track like that until I get better at taking corners before I port head or anything else for powa

 

Very nice, building the same thing, Im looking to get another b16 head thos so I can get it pnp, nice numbers tho.

Thanks for actually seeing what's going on here, the header I have now is a knock off big tube tri-y , and I am running open header. The car will be used for drag racing purposes only I am hoping to dip into the 11's with it!!! I know the motor has more in it that's a given at this point I just wanna get some seat time and get used to it! I really feel like my tuner jarvis199 did an excellent job with it. The dyno we use does read extremely low it's a proven fact , I might for fun just get on another dyno to compare the numbers.

 

looks solid. the dip can also be related to the header. pretty sure you'd be making very similar numbers on pump gas

 

Did you not read above that the dip is from my intake , we switched to a shorter intake and it went away but lost hp across the whole power band!!!!

 

Nice numbers OP. Looks like a healthy engine!
Like you stated, Dyno NUMBERS are just numbers used for tuning purposes only.
Any camshaft tuning done yet? I know you said you degreed them to spec, but was curious how much more you might have been able to squeeze out of them.
