Solid rollers sound quite nice.

Rhino79 · 07-10-2015, 11:55 AM

Here the before and after. Cam swap was only change. Same heads.

That torque curve is pure sex!! That is what launches the car and get's it going down the track. Not peak HP #'s like so many advertise.

Rhino79 · 07-10-2015, 12:11 PM

The new cam tq curve is the thin blue line hp is thin red line. It made more tq. Just didn't peak till 5700 on tq. It only sees the tq curve 1 time during a run. The rest of the run is 7300-6300

I agree 100%. I fall to as low as 94kpa after 4200rpms. Power continues to climb regardless, but there is power left on the table.

Once again, nice results Ryan. LLSR is proven once again. Nice job on getting the t&d's to work with the PRC255's. I meant to message you the other day about that.

USAFS197 · 07-10-2015, 01:31 PM

Whats the rpm spread between the two cams when they start to make equal torque?

Pro Stock John · 07-10-2015, 02:07 PM

Wow that's awesome, go get it Steve!

Rhino79 · 07-10-2015, 03:04 PM

Equal tq at 5200.

Punisher_ATX · 07-10-2015, 03:18 PM

Nice numbers but a little disapointing to me considering you made the same power and WAYYY more torque in your vvt4 ported stock heads auto car with hydraulic. Am i missing somthing here...

Rhino79 · 07-10-2015, 03:50 PM

Well, biggest thing there is that my ss4 combo had more compression. This is about 10.8 vs my 11.4. also this is not a solid vvt. Car had previously been converted by another shop

My ss4 was no punk though it's a big hyd. Lol.

Mmkay. Are these two pulls started at different rpms? I'm just making sure I'm reading this chart right. I'm thinking I'm seeing things and there's a substantial low end power loss there and not something more obvious like, starting at a different rpm, etc.

Rhino79 · 07-10-2015, 05:44 PM

There was a loss below 5000. The tq and hp cross at 5252 on the graph which is about where both cams made the same tq.

I built the setup to turn rpm. Make power up top, where u need it in a drag race.

USAFS197 · 07-10-2015, 05:54 PM

Fair enough. Makes sense for a drag setup. I was just doing a self check and making sure I wasn't going crazy.
