Sonny's 2.3L 633whp FP Red Single Scroll C16
 

First, I need to apologize for not getting this new thread done sooner to help clear up confusion on the last one.

Sonny had made 467 on S1s and c16 on a stock 2.0L after evolving his car over the course of a year or so. Eventually there was an oil pump failure and it was necessary to do a built motor. The choice was made to do a 2.3 to keep his original block, get the best headgasket sealing we could, and keep the price reasonable.

This car is still a monster, makes great power on the daily, and with one or 2 small mods I think could make more. As far as more power on C16 there may even be a little left there though I am thinking not much. One thing that I am very pleased with is that it makes almost as much on WA 89 (cali 91) as it used to make on C16 on the stock motor and small cams.

That is awesome. I had Mr. Brown build me a 2.3 long block, which will be using R2 cams & an FP Zephyr.

Are these the cast or billet R2 cams? Any benefit to using the billet over cast?

These are cast. There were numerous reasons to switch to the billets and one is production tolerances are even closer than they used to be. The cam grinding equipment has always been CNC but there is more ability to adjust the lobes than there used to be. I feel that its not going to make any difference in power though.

That spool up is great for the single scroll!!!!

Being a 2.3L definitely helps.

This graph/car interests me since I will have an MHI Red on a 2.3 and E85. Interested to see differences in spool up and curves...especially with open scroll vs. twin (our mods are a little different though)...

definitely some ass-kicking power. would love to drive that evo to get a feel for transient response. i'm also curious about that clutch. noisy? easy engagement?

interesting choice of injectors considering all the high-end parts.

i'm wondering what you'd change to make more power. if the full-race manifold has 1.25" runners, i could see swapping that for 1.5" runners. maybe fic1050sp injectors if e85 is not in the cards? 65 or 70 mm throttle body?

It already has 1250 injectors.


I think the buschur ported TB is 65mm..

I was assuming that the 1250s are the older low-Z that leave a bit to be desired for consistency.

ok.

Awesome setup. Bet it is an animal on the street

Could you expand on this subject?

Its just that they are not the best for low pulsewidth conditions, i.e., at idle and cruise. Its a little tougher to get consistent idle and closed loop cruise trims. Injectors have come a long ways in the last 5 years, and while at one time the older low-Z technology would have been considered very good, now they are more middle-of-the road with the high-Z options generally performing much more consistently at low pulsewidth. Price for high-Z is much higher though as well. But let's not get off-topic.

Correct its 65mm TB

the injectors are left over from when i just put the red on the stock motor, they seem to be doing the job.. Idle and Cruise are great.

The R2's in a parking lot took some time to adjust to.

e85 is not an option, i have no pumps even remotely close to me.

Meth is next to help this pump gas get some life.

twin disc is loud as hell, annoying to drive, decel noise sounds like ****s broken and it engages like an on/off switch.. Hooks great though and its lasted 12k miles so far.

What's the compression ratio of the piston? 9.0:1?

Probably 9:1 since the car was intended to run and make decent power on pump gas.
