Thread: 6262 dyno Results and freeway vid p30

Well I ordered my new cams today from Greg V. I am going to take some advice from Miko and go for the 20V cams. They should be here by the dyno day next month and we can see if I can make more power on the dynomite than last year's 421whp.

I am going to miss the SR16 cams, but I am excited to see if the 20v cams will have any gains. They have similar duration, but more lift. Also, they have a little less overlap which I suspect will help my top end power a little more since I am not using a larger turbo.


I have just finished the battery relocation to the trunk. Here is my distribution block.

Here is the battery in the trunk, just need a box to cover it and hook up the vents. The main power is fused with a 250A fuse.

Here's the car as she sits. Just needs some coolant added, and clean up some wiring and vac lines and we are good to go.

I am really excited to see how the cams perform though. The SR16 cams seemed to hit earlier than the 2.0 cams and allowed for quicker spool. The mid range has lots of tranny-breaking torque, an increase over the 2.0 cams. But I remember the 2.0 cams holding better up top. I was going to do a back-to-back comparo but I don't think it is worth the dyno time.

OE SR20VE cams
Low lobe INTAKE - .331" LIFT /220º DUR - Low lobe EXHAUST -.260" LIFT / 244º DUR - OVERLAP - 0º
High lobe INTAKE - .421" LIFT /264º DUR - High lobe EXHAUST -.407" LIFT / 268º DUR - OVERLAP - 48º

OE SR16VE:
Low lobe INTAKE - .279" LIFT / 200º DUR - Low lobe EXHAUST - .313" LIFT / 244º DUR - OVERLAP - ---º
High lobe INTAKE - .437" LIFT / 280º DUR - High lobe EXHAUST - .437"LIFT / 280º DUR - OVERLAP - 70º

OE SR20VE 20V:
Low lobe INTAKE - .398" LIFT /228º DUR - Low lobe EXHAUST - .327" LIFT / 244º DUR - OVERLAP - ---º
High lobe INTAKE - .472" LIFT /278º DUR - High lobe EXHAUST - .439" LIFT / 280º DUR - OVERLAP - 57º


I will have tried every factory cam for the VVL other than the N1s on my car. Hopefully the 20Vs will kick ass. I have a feeling that as the backpressure builds in the turbine housing with RPMs, it overtakes the intake pressure and chokes the engine. The SR16 would prob work with a 1.06 open housing well. It just seems like they respond better to having less exhaust restriction.

To bring up the point of the tune, I will not be getting "tuned". I am just slapping parts on. But Others have had good results, and I'm not looking for anything out of this world. Many people have used the JWT tunes, and I'll leave you with this quote from Mike Kojima:

Coheed, wanna give me a deal on the 16ve cams. Hit me up via pm. LMK i will take them off ya for my build. Looks good and cant wait to see the results man. Youve always been one for testing thats for sure.

You got em if you want them.

I really wanted to try something else, before upgrading the turbo. I want to max out this setup on 22psi or so, and make 400whp by 14psi (12psi sea level). I think I could do it eventually. I have been on the fence for a long time as to upgrading the turbo. But I just can't justify it when so many other people have been able to make 500whp on the same turbo. And I love the response of this thing!

I was thinking of keeping the 1.6 cams and putting on the open housing 1.06. People say it would be really laggy but I think it might actually work well. The 1.06 in the 30r flows about the same as the .82 in the GT35. There is less intake mass flow, and smaller wheels, so the spool should still be decent. Or it could be a turd. Who knows.

Perhaps the current setup just needs some gentle massaging.

hit me up with a price for em and ill get them off you in the next couple days or so.

I am very interested to know how the 20v cams will go compared to the 1600's - I did do a quick search to see if you had a build thread but couldn't find it but what pistons are you running?

he has a build thread, i think its called Coheeds blogger or something along that. Huge thread, tons of info. lol. Just search his started threads and you will find it.

My bad - Found it, have already read right through it a few weeks back haha.

8.5:1 JE pistons, designed for the VVL motor. They are nice pieces. I sometimes wish I went for a higher compression, but I love the flexibility the lower compression gives me. And the bottom end power that is supposed to drop... didn't. It really doesn't feel any different on the bottom end than my 9.5:1 build a few years back.

I am interested as to how you will do with the 20Vs good luck ....I still want to try mine but I will have to change pistons ...
