222hp DOHC overrated?

[Kibwe Walker]

IMO the emissions hurt the 3s's that came to the US.

Remove that emissions block and you get closer to the cars stated numbers.

Probably going to get the flame again but whatever. I had all 3 different motors over the years DOHC, SOHC, and now DOHC TT.

The thing that the DOHC has over the SOHC is that extra 1k rpms in the power band. I would say that up to about 75 mph there is no real difference in performance between the SOHC and DOHC. Stretch your legs past that and the DOHC shows itself with a nice clean walk. Never forget the weight because a SL or RT model will usually carry more weight via options and drivetrain via rims and tires than the SOHC counterpart.

Modded there isn't much to gain out of the SOHC other than sound. The SOHC can sound very mean with a exhaust, intake and that resonator removed off the intake. DOHC modded is pretty quick for that matter. In my SL I had: K&N, full 3 inch fireman exhaust with flowmaster 4 series (evil sounding), aftermaket rims (lighter), lowered suspension, and aluminum FW, and crank pulley.

Best I ever got out of my SL was 9.2 @ 77 mph in the 1/8th. I even beat a 350z when they just came out with my SL. Once with me driving and the 2nd time with me driving the 350z. Yes I watched my SL walk ever so slight going up to 135 ish mph. That said it was pretty strong until 4th gear. If I lost a race in my SL it was usually going into 4th. This was the area where I lossed to a modified prelude, a civic with a H22 swap, a s2k, and a 01 mustang GT. The GT did the most damage against me.

Onward to the TT. Got my 93 completely stock and in that form it went 8.7 @ 81 mph at the very same track where my modified SL went 9.2 @ 77 mph. Talk about pissed completely stock in the middle of the summer heat it was already half a second and 4 mph faster in just the 1/8th (hint it only gets uglier the faster you go). You want to think its just the launch, nope there is a obvious power difference.

The power difference is suttle enough to where you won't feel it going from my modified SL to stock 1st gen rt/tt but driving my SL home I quickly realized 2 things.

1 The rt/tt had a much stronger clutch, I mean I nearly put my foot through the floor board when I hopped back in the SL.

2. On the same roads where the rt/tt was catapulting me and my friend to 130+ speeds with EASE, my modified SL was struggling to get just me to just over 100 in the same distance (I had spots marked off by memory).

The dohc TT suffers a bit from the emissions because getting all those cats out of the way sure does wake these things up. I mean seriously, night and day difference with just a little gutting and a DP.

FI just makes things better. FIPK on a NA 2-5 hp, FIPK on a TT is 20-30 hp, full exhaust on a NA is maybe 10 hp, full exhaust on a TT can be over 40 hp.

Seriously, FIPK, and full exhaust with the typical boost controller treatment on a healthy TT is over 300 AWHP and maxxing out the stock fuel system which maxes out just past 400 hp for reference.

You guys with NA's should do yourself a favor find one of these tt's upgrading to tdo5's and start picking up some TT parts cheap. Find a TT ecu and run wastegate pressure (6 psi), with 9b's to your hearts content. The stock tt ecu is right at home with 360 cc injectors and will keep knock away at only 6 psi.

That 6 psi from 9b's would be faster at a better price than anything you could throw at your NA. Oh well thats enough for now.

A friend of mine like 2 years ago had a shop tune his bolt on SL with an safc and got an extra 28 horses

not gonna happen on a non turbo

Hmmm, well my SOHC has since been modded, at considerable costs. I put the Ripp Mods SDS SC on it. It went from 149, to 260fwhp, and that was before RayP figured out the MAF issue and tunned it. I suspect now its close to stock VR4 levels, maybe more...the little SOHC can perform very well!!!!

Hey dip shit, mine wasnt meant to be funny. It was meant to be informative. You tried to be funny and failed, miserably at that.

I could see it.

We tend to be tuned on the rich side of things stock. I leaned my SL out by pulling the bottom middle honeycomb into fooling the MAS. More air was going by than was being registered. You can actually feel this mod with the leaner fuel trims.

I would imagine the results would be better if they actually had it on the dyno and could monitor the A/F ratios vs ghetto rigging it the way I did. All I could say is my SL was substantially faster than stock but still slower than a stock 1st gen vr4.

5-10 hp I could see, but 28 WHP on a NA... no fucking way. Stock NA's dyno 170, Ray who we all know is a master at tuning couldnt even tune a highly modded NA with cams and everything to over 195. Think about it

I was thinking total not just safc.

For instance stock the car made 170 and after all the modification and with a safc when went back on the dyno it made 198 or around 200 WHP which what I think DOHC na's are good for without FI.
