Re: 4g63t modded estimated awhp?

If you're running e-85, at the least run 880 injectors. I really don't think a SMIM is necessary. Plenty of people making a lot of power on stock intake manifolds. I liked my small 16g turbo, made quite a bit of power (but dyno, also had hks 264's) but I was also running 20psi, that was spiking to 24psi. I'd say a ported s16g, with adequite fuel, could make high 200's at db. It's still gonna be very fun to drive, mine sure as hell was. But at 15psi, expect mid 200's. Oh need to add a wideband to that list.

Btw-have that front mount still, I can take pics today.

Re: 4g63t modded estimated awhp?

For comparison, this is the dyno sheet from my old 16G setup on my 1g:

Hahn Super 16G (8cm^2 exhaust housing)
-FMIC
-650's
-FMIC
-3" exhaust
-MBC
-272's
-walbro 255lph
-bunch of other things also, but these are the basics.

This was on 91 octane at 23 psi on DB's Dyno Dynamics

Re: 4g63t modded estimated awhp?

again, safc isn't meant for 850cc You will be disappointed IMO
an SAFC is meant just for those 550-650
get a 2g mas with those injectors and tune out with the safc

you are pretty well setup for pump gas!

Save your money for DSMlink and upgrade later when something blows

I loved my S16g when it was working and when I had a similar setup.

Then I threw 272hks
A standalone system
E85
1150cc
I think I maxed it out...
It was instant spool and I loved it

I hate the turbo that I have on it now. Laggy...
Stupid free v trim...

Get a 2g MAS (pm me I have one with pig tail)
550 or 650cc
Your SAFC will be fine on pump gas and the combo of a 2g mas with 550cc injectors
(2g mas sees 10% LESS air then a 1g mas. Put in 550 injectors will yeild you 20% MORE fuel and then use the SAFC to correct the 10% difference

correcting using the safc for 10% isn't that bad. Probably run like stock. People just use the 550+2g mas just by them selves without safc and some are fine.
650 will have a 30% increase of fuel 2g mas sees 10% less air meaning you have to tune out 20% with the safc, which can be done... but doesn't run quite right.

There is nothing wrong with pump gas. I would wait for a bigger turbo before hitting the E85 unless you want to fully max out that S16g

hope I didn't confuse you but just showing you what you have for options

PS you may be thinking you want 300 or more horsepower, however take it down to the track
you will forsure hit 12s in which is one quick car then for minimal mods...

In my experience with E85, you can't get the full benefit of it unless you have a standalone. You have to adjust the timing tables (which SAFC doesn't do) and other things before you really see the benefit of 100~ oct. Plus it changes in the winter (which I haven't seen too much of a change but I haven't driven my car that much) so you need something to tune before switching.
Some people will disagree with me about needing standalone but this is just my opinion.
