Since I'm getting close to a final design for a single muffler option, I decided to put my OEM intake back on in order to repeat my tests. Even though the OEM Intake doesn't make as much torque as the PWJDM, I really just think the torque curve of the GernPipe and PWJDM combined is less enjoyable than what I get with the OEM intake. Basically, the PWJDM was a great combination with a conventional exhaust, since it gave a nice boost in torque in the range where the conventional exhaust was robbing torque. However, since my midpipe doesn't rob power in that range, I would much rather have an intake that provides gains higher in the RPM range.

Here are the torque plots from a controlled test I did last night.

 

BTW, I would LOVE to test my mid-pipe on an S2000 with variable valve timing! I believe it would provide truly awesome results.

 

You mentioned on another thread that it doesn't sound good with the K&N FIPK. Would the K&N also hurt performance over the OEM intake?

 

The sound was from my car, and it is just that with the lowered engagement you are in VTEC more and it is loud.

 

I'm really just not a fan of the FIPK, since it sounds so bad with a low VTEC engagement. That opinion has nothing to do with my midpipe. Even with a test pipe, which allows a ~3600 RPM VTEC engagement, the FIPK sounds bad.

However, the torque curve of the FIPK combined with my mid-pipe was great. It doesn't have the issue that my PWJDM has (too much low end torque).

 

& I just got a 70RR.......... $%*&

 

???? I thought that's what VTEC was? you mean variable cam phasing? I'm confused

 

I was referring to the Dcraft iVTEC conversion.

Yeah Gernby i just sold my PWDJDM intake in prep for my itbs going on soon, i have the stock intake on there and i misses the PWDJDM lol. Nice to see stock data. I know thats what everyone is after.

Also was thinking torque dream machine. iVTEC+51mm ITBS+Gernpipe=fun!

 

How soon are you getting your ITB's? I am looking for a few "key" opportunities to have my midpipe tested in "key" setups. If we can work out an arrangement for me to ship a test unit to you for independent testing, I would compensate for it.
