Well, just got my motor out the shop and its only pulling 217hp and 178 tq. that was with an open header too..... bottom end was sleeved, new rods,pistons, head was p&p, crower stage2,crower valvetrain,s2 im, 350cc, WTF? what could be wrong?

 

You left out the most important thing. What are you tuning with?

 

I'm kinda in a bad mood but still...
I'll tell you what's messed up.
You don't even post up a dyno graph so we can analyze it, and all you post is peak power numbers. You tell us all this worthless info of blah and blah mods, but you leave out the most important stuff like tuning electronics and even ignition, and compression ratio.
Dude hook us up some on your setup, then maybe someone can help.

 

haven't got a chance to get the pix yet and compression, but tuning with hondata s200 with p28...will post up dyno and compression soon sorry...electronic using msd digital 6

 

you dont know what compression pistons u used?

 

what header you using? what compression? Who did the p&p?

 

im using a DTR 4-2-1 race header, 11.5cr JE pistons and the head was done by LDL speedshop block was done by Golden Eagle

 

217whp is pretty good for such low compression in my opinion.

post up your .bin

 

What kind of dyno?

Exactly 217 whp and 178 tq are good numbers. A few things might be able to be done to bump up the peak hp, but those #'s aren't anything to complain about. Post up your dyno so we can analyze it.

 

217 whp on 11.5:1 with crower stage 2s is not bad. There might be a little power left in it, in other areas but not a whole lot. I'd be content.

 

you spent a whole shitload of money for stock type s compression ? thats pretty damn silly if you ask me.

I agree. If you went 1 point higher I bet you could have easily hit 230whp.

Post your .bin up if you can... I'll take a look at your timing tables. It's not all about PEAK whp... 217 is pretty damn strong. Be happy... there are always others out there with more power than you.

 

yep, numbers look pretty solid to me.

he has a point.

 

as far as other crower stage 2 dynos ive seen ..its one of the higher ones ..and torque seems high ..

 

Type S compression is 11:1 . . . isn't it?

I say the peak numbers look pretty good - depends on what kind of dyno it was, though. And are they SAE corrected?

 

definitely liking the torque numbers tho. ~40ft lbs over stock....i could handle that.

 

Man, I would love to have 217whp in my Prelude.

Was the sleeving and the rods necessary?? Just curious.

 

Great TQ.. Thats not to bad though

 

We still don't know what kind of dyno or even have a dyno chart to look at yet...

Do you really think he got 178wtq on the 87mm bore? Piston rings don't seal well with 1-1.5mm piston-to-wall clearance.

Heres a few questions that may seem meaningless to some, but...

What were the final flow bench numbers of the head you are using?
What were the gram weights of the pistons and rods you used?
What springs/retainers did you use?
What valves were used?
What are the primary and secondary lengths, 4-2 merge collector inlet/outlet diameter and 2-1 collector inlet/outlet diameter, final transition diameter of the tailpipe on the header as well?
What intake manifold are you using?
What throttle body are you using?

All important factors... Theres more to making power than compression and cam specs... People often overlook component weight and a couple of other key factors (header specs in conjunction with your set up, intake manifold specs, TB sizing, valvetrain mass/pressure, etc)

nd please, post the HP, TQ and A/F graphs.

I agree twice, be happy with what you've gotten, and this thread sucks until you post up a chart and a tune.... and the rest of your info... for NA setups i usually like to see all the little details

 

yeah, answer Innovations questions and the anwsers you seek will appear (sounded weird)

217 is good, but piston choice was poor,

 

Just out of curiosity guys, for the sake of argument ... if the car was intended for daily driving and not pushing towards the limit of using race gas, is 11.5 CR still a solid choice?
