A-B Dyno Testing ZZP Stage II Ecotec Cams // Cobalt Build Episode 18

[@christianshafer1886]

I cant wait to see the different pulley size comparison video! It will be very interesting to see how much power is gained by dropping each pulley size.

[@Dxb6756]

I agree! I can’t wait to see how much power it gains once Tyler drop in pulley size.

[@Siviqs]

the blue devil returns!

[@deebalt071]

Little side question. Is it normal to do the pull in 3rd gear opposed to 4th gear in these cars?

[@codygermscheid7081]

Definitely try out some different pulley sizes but I would be curious on a test between a factory blower and a ported blower and an LS4 throttle body

[@D.O.I.N.K]

He’d gain either way Not sure ifZZP is porting M62 blowers though? There was a great outlet / inlet port design floating around the forum that gained quite a bit of power.

[@mccartyb03]

@@D.O.I.N.K Category V did mine. I just ditched the LS4 TB though, the drivability sucked for what was probably a small gain.

[@D.O.I.N.K]

@@mccartyb03 There’s a learning curve for sure with the LS4. Some love it, some dont. The gain is larger the higher the engine revs.

[@mdhaynes86]

I would like to see some back to back tests on a ported blower and LS4 throttle body.

[@rosslawrence4628]

E85, intake, exhaust, A test 254hp, 211tq. You forgot to mention what injectors you are running, as the stock green 32lb/hour ones won't support E85. I'm at 98% injector duty cycle on E10, with the stock LSJ. Are you running Siemens Deka or Bosch EV14 injectors?

[@gbrunner24]

If you run through our previous videos in the series I cover all the bases as to what's on the car. But for ease for ya: Siemens 60# injectors, ZZP cold air intake, ZZP mid length header and 2.5" exhaust back to the stock muffler, pump E85, dual pass end plate, option B, ZZP stealth heat exchanger, ZZP S1 intercooler pump, and my tuning.

@@gbrunner24 Now you have me binge watching your cobalt build. Not sure how I missed all this, but nice content!

[@chrispisano5791]

The spring compressor is what I wanna know about. If I decide to get the 82# springs.

[@ZZPerformanceChannel]

We'll have an install video out next week!

[@jadenharris932]

Did you have the ati balancer and neutral balance shafts?

[@gbrunner24]

Nope. Stock crank damper and stock balance shafts are in place.

[@jadenharris932]

@@gbrunner24do you have a lot of vibrations?

[@gbrunner24]

@@jadenharris932 Considering I have all 4 billet mounts, there is a good amount of vibes over stock, but it really doesn't bother me at all.

YEEEEEEEEEES

[@thomasmixon5555]

What wheels and tires do you have would love to know

[@gbrunner24]

They are Enkei TS-10 18x8 with 215/45/18 Toyo Proxes A40. The car has a 5x114.3 hub swap on it.

[@Pudding175]

Tyler, are you running the ATI crank pully or stock? Im curious what sized belt you are running. I have the ATI with the factory supercharger pully on my 05 redline and can't find a belt that well fit.

[@gbrunner24]

Factory crank pulley and OEM length belt at this point. Overdrive ATI or under?

[@kirbyswarp]

How many degrees of timing are you running?

[@gbrunner24]

I like to keep it right around 21°. A test had a little more timing, ended up at 22.5° around 7k. B test was dead on my 21° mark out the top end.

[@kirbyswarp]

@@gbrunner24 Did you try running any more, or did it stop making power?

[@gbrunner24]

@@kirbyswarp I did not, stopped there. Picked up about 6whp going from 20 to 21. May have made a little more going a little higher, but that 21 mark is what I like to shoot for.
