Went back to the dyno last night and it looks like my wacked-out distributor was costing me 5 little ponies and causing a dip at 5700 rpms.

Looks a little better now:

Used 1995 993 motor.

And here's the one other ingredient: Steve Wong custom-programming a chip.



Here's the sheet:



264 hp and 232 ft/lb of torque at the wheels.

foreplay

seems the chip will make a big diff ?

My RWHP and RWLBFT figures are almost identical to yours Jack @ 263.63 hp and 233.89 lbft on 1994 993 3.6l ROW engine using Steve Wong custom chip. My only additions for power are Dach X catless pipes. I do have RSLWFC and also RS pulley hub. Have replaced Disti caps and rolors, bearing and belt along with overhaul alternator bearings and new MAF.

I am up grading to DC21-114 cams next month with custom built adjustable rockers/solid lifters. Will be replacing factory springss with eibach high lift but keep factory retainers and seats. New (advanced) timing of course and then another SW chip based on dyno AFRs. I will renew iginition leads and plugs same time. I am hoping for 280 rwhp and 250lbft at the end....we will see...

Cheers

That sounds awesome. And it's especially impressive for a 94 motor -- are they the same as the American 94's?

I'm on the poor man's path -- stock 993 headers and an off-the-shelf American car muffler. I recently snapped a belt at speed and as a result went to the RS single pulley. I'd like to get the single sheave pulley on the crank, but would prefer to find a bargain on one. Maybe the RS pulley gives me a little extra -- who knows? But I can run without cats because my car is 39 years old, and exempt from smog testing.

The thing that would make a difference in the feel of our cars is my gearing, which has closer gaps and shorter overall gearing.

Hi Jack. No my engine is stock Late Nov 1993 build 993 3.6 M64.05. The 993 was launched world wide in October 1993 and mine is number 1182 (8th RHD). Our market was leaded fuel so its actually built with no cat for running leaded fuel but I swapped the hollow cats for Dach X catless pipes (lighter and make nicer noise). Being prior to year 2000 my 993 is also smog exempt.

Effectively we have the same engine except mine has no SAI ports. I have factory headers and exchangers. So I think we are running almost identical set up. I ahve recentkly purchased teh patric Motorsports alloy dual belt crank pulley but not fitted yet.

My car has the ROW G50.21 so I closer stacker first few ratios - I suspect we arent too dissimilar here. Obviously there are changes between dynos, conditions and operators at play.

Where you have a huge advantage is weight. Im 2900lbs with all luxury features intact. Id imagine you must be under 2600lbs!
