Well, the motor is finally done and tuned on 93 octane. I went to the local dyno day just to see what kind of #'s it was making. It was fully street tuned by me and probably still has some more power in it with a few tweaks. Overall, very happy with the results. Gotta give thanks to Rocket for making this project happen and DonF for his help with the piston issues and expertise!

I know people will ask the setup so here it goes:
Block:
b16A block, LS crank
86mm custom CP pistons ordered from Rocket
Eagle rods

Head:
Gsr head ported by Rocket
RM valvesprings, retainers, M24X cams
DonF opened the chambers on the head and degreed in the cams
Blox IM

Rage big tube header
Kteller 2.5" exhaust with magnaflow muffler
AEM cold air intake

1st dyno run, 8400 rpm rev limit


2nd dyno run, let it cool down, removed the intake filter, was just running the aem cold air tube, 8700 rpm limit

Did not get a torqe readout but suspect max tq of around 155 or so on this run.

I feel more power can be made with more tuning, especially timing values and a better intake setup such as a velocity stack.

Just wanted to share with everone my results! Paul

congrats on the numbers Paul

 

great #'s. hats off to donf and rocket

 

wow

 

Nice. If you get the run files from the dyno you can make your own plots and show RPM, torque, etc. What are you using to tune?

 

good stuff. what size tb are you using? any plans of porting/rewelding the intake mani?

 

nice numbers

Yeh, i'm aware of that, I just don't have the files here. Hondata s200 setup is what i'm using. It was an extra from my previous setup.

TB is a 68mm bdl unit. I don't have any plans to port the IM, i'm quite pleased with the numbers and should be fine for my daily driver. Paul

 

What is the static compression ratio on this setup?

 

i would expect more out of that build

Should be around 11-11.5

 

b16a huh... nice sleeper

Why exactly?

With that compression, and the RPM its turning i think its right around what i would expect. Plus we dont know how this dynojet compares to dynojets we may be more familiar with. Theyre all over the place.

 

LS length rods?

 

Great number for a sleeper b16a!!

Ls Crank..

Are you using LS rod length or custom length eagles?

Thanks for that, i needed it, i didn't want to say anything with that comment that he made.

I'm running b16 length rods with custom pistons. Hope that helps.

 

wow very impress on those.....and come on post up more details on those cams
also if you dont mind me asking what compression ratio are you running?

 

didn't know LS crank could fit in a b16a was it a lot of work to get done? good # 's

i spoke too soon...didnt see what his comp. was till after i posted...
either way, its still technically a 2.1 litre engine...it also has had full headwork done,huge cams,and a high end header...i would still like to see more out of this setup because it definitely has the potential to do so....look at the dyno plot, its struggling in the mid rpm range, therfore decreasing overall/high end power...
im pretty sure the intake manifold is your main problem....doesnt support the engines flow needs in high cam....get it ported or find something better and im sure you can hit 240 with it...

 

Yes, i'm pretty sure it has more potential, but this setup was done on a budget. It took me over a year to gather the parts and get it running. Overall, i'm very happy with the results, but as you stated, with better parts (more $$$), it can make more power, no doubt about it!

 

 

Thanks Paul!!! Sorry it took 1.5+ years for me to get you the "ported" head. Don was a great help and he says are a great guy to deal with.

I was wondering when I would hear from you. I guess when you have driven 600+whp honda's everything else feels kinda slow.

Yeah, you would make alot more power if you had NGK Irridium spark plugs or Buddy Club VI's spec 07 or a leaf blower on the intake and a heat gun on the air temp sensor. Good street tuning normally makes your car faster but has a lower peak # on the dyno. I guess we can't have it all.

Funny how Dynojet numbers are not the standard anymore. Maybe some direct torque reading dyno's with user inputted correction factors would be more appropriate. On Churches dyno your motor would read 263.3whp.

Thanks again Paul. Call me if you ever need anything.

 

I've been busy with things and i know you are busy with things, so i figured you would read it on here. I'll definately keep in contact. Thanks for everything and the advice. Paul

 

heh, found this thread by looking in rocket's recent topics...!

that's quite the stroker build... I wonder how high you can rev it without falling off much...

 

good build i like the set up
money shot please
