Dyno day with the HRC Super 16G

[GSTwkd]

Here's my set-up;
HRC Super16G
HRC smic
greddy i/c pipes w/ bov
S-AFC
550's
walbro 255lhp fp
2.5" dp w/ 3" tp and cat-back
ported 2g exh. mani
Vitek wires
NGK plugs(factory ones)
Injen intake w/ Weapon R filter
completely stock motor and head
using C16 gas
EVC 4 set at 26psi :laugh:

My best run was 303.71whp and 341.32wtq. My A/F ratio was 11.5, egt's were 810C, o2's .94 and my timing drop to 9 then climb straight to 20 degrees without a hick-up.
A month ago I ran the same set-up except I used 93 oct and set boost at 22psi and I got 300.79whp and 325.79wtq. My A/F was 12.0, egt's were 860C, o2's .94 and again my timing drop to 9 then climb straight to 19 degrees without a hick-up.

Now I'm happy I hit the 300whp and I'm surprised how high my torque is. But what numbers should I be looking for with my current set-up? I see that B16g's are rated from 350-375hp and my S16g is rated for 400hp. I'm curious to compare numbers with some of you guys with Big 16g and similar mods. Also I'd like to see what the spool difference is too. Judging from my readings and hp/tq figures, it looks like my IC is killing me. This time the IC only got warm but a month ago you couldn't touch it after 1 run . Looks like I'm shopping for a good fmic now. Then intake mani and head work.

I know how much some of you guys out there who love the HRC "Super Turbos" and bash it for lag due to the 10cm housing but really I cant complain when I'm already spinning the tires in third gear from a roll at 60mph. I haven't seen anyone's numbers with these turbos yet so enjoy and let the flaming begin!

 

[TRBOTSI]

I think those are some very respectable numbers. Especially considering stock restrictive 2G head, stock cams, and only a smic. Nice job....

You got this at 26psi? Timing is awesome! not bad, not bad at all....

I got 316.+++ at 20psi on pump gas at EIP Tuning with all my mod's, when we raced I was on stock cooler and GReddy's in my garage and then I'll re Dyno and then be up to race you again...DEAL?

Your cooler is killing you......
blah blah blah.....your numbers are darn good....

You gained 3 whp on c16 and 4 more psi ??????

 

[GSTwkd]

Thanks guys. With my torque being so high, how much more hp do you think I can get out of a fmic and 1g tb, 1g intake mani, and ported 2g head with cams, spring, etc...

GSTspeedracer-- whats up! you got it on the racing
My numbers I think are a little better when you look at how I ran on 93 pump gas at 22psi--301whp and 325wtq. I know my ic is killing me but how much ya think. Can't wait to see your car with the new mods

Anyone else out there with some 16g "type" dyno runs so I can compare. If anyone has any ideas or comments please let me know. Do you guys see anything that sticks out that I should look at. Thanks

 

[GSTspeedracer]

Well....actually!

I have something that sticks out.......... that you could look at!!!:laugh:


Seriously, get FMIC and then cams......should see substanial gains!
I wouldn't worry about Head until you get a larger turbo.

I think you'd hit over 350 WHP on C16 + 25ish PSI and FMIC and maybe cams.......NICEish...

I'm bigger on pump gas and WHP.....just me though!

One of my BIGGEST GAINS in Dynoing was when I fixed a boost leak, always do this before dynoing, just to make sure.....blah blah

 

[GSTspeedracer]

Oh...I have a friend 16g no fuel mods, he dynoed 230's whp.

 

[GSTwkd]

yea, I will be getting a fmic first but if I'm putting cams in then I'm gonna get all the other stuff while I'm in there. As for dyno'ing, I care more about how I run on pump gas than I do on race. But its fun trying to see what ya can squeeze out of a set-up using race gas. My o2s, A/F, and timing seem pretty good so I think the car is running to its potential right now on its current set-up.

 

[CH152]

Did all that come in a kit from Hahn Race craft like the turbo and fittings to install on a 2G? i know you can buy the cams from them too i think.

Wanna sell me your HRC Sidemount? PM me.

 

[Clipse]

Impressive... those are some really good numbers for what you have done!

 

[XTurboSpYderX]

very impressive... and from what I hear you are right about doing headwork when you swap your cams... the 2G head can't flow enough to make a cam swap worthwile without a little porting...

 

[HyperGSX]

Good numbers All of us S16G guys should make our way to the dyno.

Actually cams will help. HKS cams give more duration with the same or slightly more lift (you run the stock springs & retainers). They are also timed differently for opening and closing of the valves. The longer duration will keep the valves open longer allowing more flow in & out of the head. More time open = more total flow per stroke of the piston. I have the HKS 264/264 cams and with a totally stock 16g (no porting, unclipped) on my "99 GSX and no other internal mods made to the engine, I made 305whp at 18psi when the stock (unported) exhaust manifold & O2 housing were still on it.

 

[GSTwkd]

Thanks guys. As for cams, I believe them(264's) by themselves will give some decent gains but I only wanna put them in once . Cause I do plan on upgrading to the 1g intake/tb and porting my head with new springs and retainers. But first I need to find out which and what parts I should go with. I know I'm going with HKS 264/264 cams with my set-up but thats it for now.

How does my torque look to you guys? There's such a big deference compared to my HP.

CH152-- The turbo comes with an installation kit for 2g's. Easy install and they use ARP studs .

 

[DSMu4ia]

Small 16g, no port/no clip.

308whp (forget the torque right now).

19psi, 94 Octane Pump gas.

Greddy FMIC.

:Whoops: DSMtuners had a sticky on one forum about it, but must have taken it down.

Here's the rundown on motor parts:

16g, 2.5 exhaust (2.5" pressbent cat back) no cat, 550's, 255 fuel pump, old style afc, greddy small fmic, very very minor porting to 02 and manifold, stock 2g motor even Throttle body, nothing special. 18deg of timing advance or so.

I could have probably seen a few more whp out of it if I knew then what I know now.

If I had to do it over again, I would have done a few small thigns to that car, and drove the balls off of it. It was too nice to tear apart .

 

[GSTspeedracer]

Hey GSTwkd....

In one of the pic's somewhere, I thought I saw a M100 PDA on your seat. If so, how do you like it and the pocketlogger stuff?

 

[Bino]

From what I see, your HP isn't as high because your torque is falling off at higher RPM's. HP is highly dependent upon RPM's. Due to the restrictions in your system your turbo cannot maintain boost at higher RPM's, and therefore torque falls off, taking with it high HP #'s. If you'd have made 342ft-lb @ 6000rpm you'd have made nearly 390hp. Open up all the restrictions, and you should definitely see some higher HP figures.

BTW GSTwkd.... VERY tasteful car.

GSTspeedracer Hey GSTwkd....

Thats exactly what it was. I like it. It does what it's suppose to. Allows me to see really how the cars running. Now on the 2Gs(obd 2) we dont get knock like the 1Gs(odb 1) do, but we get Timing advance(1Gs do too) which is very useful. If your timing is pulled, it usually means your getting knock. On my Dyno runs I was getting some nice numbers. My timing would drop down to 9 and count straight-up to 20 by 7100rpms without studdering. From what I've been told thats really good for a 2G. I believe 1Gs can see up 23-24dg of timing. You should get one if you dont plan on getting DSMlink, AEM,Haltech,etc... cause its really a must have kinda thing.

DSMu4ia-- Nice numbers. See your numbers really makes me wonder how much more a fmic will give me. I was told to get the small greddy cause it works great and fits good in my fascia but I think I'm gonna get the HRC fmic w/ 2.5 piping after seeing how cool it stayed on Dyno Day in Dave's car.

 

[GSTwkd]

Bino-- Good post. Do you think my torque falling off is from my IC? I thought turbo cars usually made the most torque down low from when the wastegate first opens?

Here's my dyno sheet if anyone wants to see it.

Yeah, show the what small 16g Can do! #@%#@%#@%#@% a bunch of poorly designed hahn turbos. People make 500 hp on 7cm red's and yet 16g's need 10 cm housings? Um, yeahhhhh

 

[GSTspeedracer]

I just purchased pocketlogger,
now I gotta get the M100 ( $60 ) on pricegrabber.com

 

[kyvahe]

I'm getting my car dyno'd probably within the week, i have a super 16g on but no fuel mods. I don't like to run over 14psi but if i put in race gas (107-117) what kind of boost do you think would be safe to run? GSTwkd nice run by the way, those are some nice numbers!

Probably about the same. Without the ability to put more fuel into the engine it will probably run too lean under boost/power. The higher octane will not save a TOO LEAN condition from damaging the engine. Do the fuel mods before you go any higher. May already be too lean at 14psi.

I ran 1.6@113 on 450 cc injectors with uncol 110 octane and 20 psi on a tdo6 20g.
Id say run ~18-20 psi
