Why? Ford doesn't. Roush doesn't. If your engine is already open, like doing cams, sure. Otherwise I wouldn't worry about the stock OPG's one bit.
With how brittle the OPG and CS are from the factory the higher RPM will destroy them. Just a matter of time and lots of info out there on the subject.
Really? 700+ horsepower roush uses STOCK OPG's. With a FULL factory warranty. You'd think they'd offer that if they thought the stock OPG's are no good? Phuk no.
A Roush stage 1 is rev limited at 7K. I can take mine to 8K and feel comfortably doing it everytime with my OPG/CS and power mods.
Only 750hp lol, yet still on the STOCK OPG's. The only well documented things I see are people putting to much tension on centri blowers cause the OPG's to break only after the crank snout snaps on 850+ horse engines, and those bouncing off the limiter like a vaping honda phuk boy. As for RPM, what's the GT350 spin too again? Ain't nothing special about those OPG either. As for a couple hundred dollars of insurance that's a LOL, cause if you have to send it to a shop to install (which is POINTLESS unless you have cams too) that's gonna run you what? $1500. I have yet to see all these 100's and 100's of OPG failures or even a FORD TSB on it. It's fine YOU don't care. Just giving relevant information instead of facebook/forum warriors advice of 'you gotta change the OPG'. To the OP, you'll be just fine.
I don't think I was spamming that video. It is a good video. This is a DISCUSSION BOARD. What's better, for a guy to come on a discussion board and say "CJ is king" and give absolutely no details or proof, or for us to have a discussion where everyone has learned the following:
Stock cams start to show a power drop off in the low 7000s, sure the CJ manifold will still make more power past that point, but it's meant to shine upward of 8000+. Want to maximize the setup, swap out the cams that bump up the power band. I do not see the CJ being worth it over a ported 18 or a GT350 manifold on stock cams, not for the money.
Well put. Thanks for the info.
A few questions:I actually have the CJ and I can't speak for a manual transmission but it simply works on an A10 in Drag Mode at the track. My current tune (on stock cams) shifts at 8,000. To get the best times, I was already shifting at 7,800 on the stock manifold as well. The fastest N/A cars have a CJ on it. Simply put, for a 1/4 mile application, the stock manifold will lose against a CJ with all other mods being the same. And for icing on the cake, it looks much better than the stock manifold.
No doubt the CJ is the beast of em all. One other aspect of this is you have a 19 with a Gen3 engine. Gen3 flows more and the manifold breathes higher up in the RPM range versus the 15-17 cars. So that's probably why you were still getting the best time shifting up at 7800 when you still had your stock manifold.I actually have the CJ and I can't speak for a manual transmission but it simply works on an A10 in Drag Mode at the track.
