Clemson Sports Car Club

This car belongs to Jinx. He brought us his Civic for a dyno tune. This car is an SCCA Solo car, runs in the Street Prep class, and has won numerous national championships. He recently upgraded from a D15b7 to a D16z6, and added a few bolt on parts.

Here is the setup:
Stock D16z6
Hytech Header
Edlebrock Intake Manifold
OEM Honda Clutch
Lightweight Flywheel



For comparison, a stock D16z6 usually lays down around 105 to 110 on our dyno.

20whp from intake and header... not bad at all.

not really just intake and header.
he gained 20 whp from a cold air intake, exhaust, intake manifold, aluminum flywheel, and header.
not unheard of any 4 cylinder.
the header retails for over $1000, i'm sure Mr. Jordan got a sponsorship price, but you do get what you pay for.

my neon after tuning is making over 30 whp than stock with nearly the same upgrades.
the torque is actually very strong that d16, i'm sure he is extremely happy with the SCCA's new rules on update backdate for drivetrains/engines for 92-00 civics.
the car was extremely competitive with the smaller 1.5 in it.
nice power curve, still has almost 110 whp at 8k rpm.

what was it tuned with besides the obvious adj. fpr?

dang ur right... thats like a 20% increase from 2 bolt-ons

It was tuned on Crome Gold Via a chipped P28 ECU

READ!, it's not 2 bolt-ons, it's 6 bolt-ons.
and as i mentioned, put a baller header on any 4 cylinder, and you'll gain a good bit of power after tuning.

Nice tuning job TDC!

I was going to say the same thing Dave...reading ownz

Ari is going to make me 2 headers for Sunny D, one that is hytech like and the other I'm letting him try out something a little different. We'll see which makes more power.

Gaining 20% from any number of boltons is impressive, and you certainly won't get that from a mazda BP engine
And it depends more on the engine than the number of cylinders. Sure, if the header is a big restriction, then the motor will see a good improvement. But if your car has poorly designed heads, like my mustang, then bolt ons really wont do much of anything. 281ci and all it's got to show for it is 190whp from the factory, and they run out of breath at about 5500rpm. My PI heads improve that tremendously, but still not great.

my oem heads, with the PI head gasket laid on top for comparison


BTW, what does a good Honda head flow in CFM? should be comparable to a V8 head, right, since a v8 head is flowing to 4 cylinders?

For the record, this particular setup was predominately tuned with the fan off and sometimes on the low setting in order replicate heatsoak conditions that the car would experience at the track. Intake air temps were on average between 100-115 degrees. We usually don't tune with the fan off but for this vehicles application, it was the logical approach. We suggested a hondata heatshield gasket and he said he had one but leaked so he took it off. We then suggested to Hondabond the Hondata gasket. Should help considerably with heatsoak and to maintain consistency.

Stock K series 3 lobe motors flow 290-295cfm in bone stock form.

not fair!,
i think he was asking about the d-series head.

giving us the information for a K-series is like me asking you for a simple handgun and you providing me with this:

Well either way, my PI heads (the improved ones) top out at around 160cfm intake 138cfm exhaust. Granted, it's a 2v motor (4v mustangs get a whopping 235cfm). Either way, a poor design. Stock 94-97 1.8L miata flows 160-180cfm. Makes sense to me, at least, that crappy heads would lead to crappy bolt-on performance (because intake/exhaust arent really the limiting factor)

ROTFLMAO!

I searched and searched but no results so I thought I'd at least show something that's current and widely used in the Honda/Acura line-up.
