Although this is not a turbo engine, my favorite forum is FI so here it goes. The cam should work for a wild turbo set though. (Hope this is okay with you Dustin )

My mechanic just informed me that he was able to lay down the following power figures and track performance with the HS non-Vtec SOHC cam (code name NC15).

131 whp NA
115 ft-tq

This was enough power to motivate a 1400lb CRX to 13.77 at 103mph in the 1/4 mile at Bakersfield. The owner of the car has the run taped.

Engine is (All Stock parts so building an engine like this is very repeatable.)

D15 Head milled 0.060
D16Y8 Intake Mani
D15B Bottom End
ZC Exhaust Mani with LS B-pipe
No Cam Gear.
90 SI ECU with 7.2K rev limit. (Engine pulled hard to red-line.)

Valve lash was set at 0.010/0.08 int/exh so more power can be had be tightening the lash a bit. Every 0.001 lash reduction gives the cam about 1 degree more duration.

Also since it had no Cam gear the cam was ran slightly retarded so the power band favored the upper rpms.

Here are some pics of the cam:

Specs are 265 duration with 10.4mm lift. Ramps are mild enough for use with stock springs.


Price is $275 plus core retail I will have dealers so the price will be cheaper through my dealers.

nice...........what are the stock D15 cam specs compared to that?

hows the idle quality with that cam?

and of course............whats the price?


[Modified by non-VTEC, 6:01 PM 9/13/2002]

 

Stock is 210 duration 9.5mm lift with much milder ramps.

Idle sounds like "ba bub ba bub bub ba bub" this can be made smoother with a by advancing cam timing.

 

wat about a vtec cam?

 

Already in the works. Just need to get some springs to handle the extra lift available on the Vtec cams.

 

how much $$$

 

See top post. Vtec cams have not been priced yet.

 

sounds good let us know man.

 

lol nice sound u making

 

Let me know when the vtec one are offered for the y8's..
I was looking in the Zex cam for my soon to be turbo setup..

 

change code name to NC-17

 

That's for the bigger cam that will be developed.

 

With that, anybody want a free d15 bottom end? Its taking up room in the ga rah hay.

 

i presume emissions are shot with that cam?
just curious.
stan

 

Yeah, "This product is for non-highway/off-road road use, please check with loca regulations...blah, blah blah".

 

sounds good :D
how's the power curve?
stan

 

Starts to scream at 3,200 rpms and then screams louder at 5,500 rpms.

 

Ah hows it work with forced induction? Overlap that comes with aggresive N/A cams is not good for FI ... It would have to be FI specific .

 

He said it's not for FI.

 

The lobe centers on the cam would have to be widend a bit.

 

so how about a d16y7 with a 50 shot? Would it work as well in this aplication, I H E ????

 

Yes, this cam is available for the Y7. Will be lethal with a 50 shot. Just make sure you have a good clutch to handle to power.

 

how much gain on a interally stock D16A6?
gutted cat,k&n,advanced timing,89 teg ecu,and soon header and plug wires.
