Hmmm, vtc actuator rattle/grinding at low mileage. Mine didn't do that until over 120k lol.

Seriously i know you didn't listen earlier, but It honestly might be worth it to go back to your stock intake, or something like the PRL short ram at the very least.

The guy i asked has done it for 8 years. 80 grit, uniform finish, remove all casting. removing all casting removes less than 1 mm all the way around, and you're not changing the shape of the runners. Just trust me and do it like that my man, i promise it's good! You're arguing with my...

You need to sand all casting marks off to have benefit, make sure the sanding is uniform and don't use higher than 80 grit. You're fine :D

The difference between 175 whp stock and 200 whp after mods is large. There are some areas where you'll gain 20-30 ft/lbs of torque over stock with a downpipe and intake. All in all, you should be happy it responds that well with only 2 modifications lol.

These engines do not come close to making a true 230 whp. If they did you'd see 103-104 mph trap speeds. And i haven't seen one do that yet. i've seen 101-102. I'd guess those cars make around 210 whp. I mean the guy that is making 240 whp on 7 psi trapped 105, so for reference you'd be...

Just like the 8thgen, if you keep all your mods on the exhaust side and keep the stock airbox (or just delete the resonator off the stock airbox and leave it mostly stock) you end up with a better performing vehicle until you do get tuned.

drop in, when referring to camshafts, generally refers to 2 main things. 1.) no springs and retainers required 2.) they will idle like stock They usually claim it will work on stock ecu, which technically it does. It just doesn't run well.

Yeah, try running a drop in cam on a honda with a MAF sensor and see how it works out. Hint: it doesn't. This isn't an old honda setup. It's a new motor, the strict emissions requirements really mess with adding modifications without a tune. You can think that a stage 1 cam will work...

I'd get rid of that intake and run a modified stock box and see what happens. The barometric pressure and air density went up yet your trap speed went down. That tells me something isn't working very well...

these engines make more power at 200F coolant temps than they do at 160. So long as you keep the stock thermostat and run a better radiator you shouldn't have too much issue.

Please make sure whatever you do it preserves the entry angle for the airflow @ 7 degrees.

lol @ without a tune. Do you think camshafts are magic? :D I still can't believe there's people out there trying to run intakes without a tune on these cars, just end up losing horsepower and making the car run terribly.

They reground the stock cams, so they were limited, but they gained quite a bit of both duration and lift. I think it'll take you guys a few different grinds before you find one that works well. Still looking forward to results :D I mean 8thgen si's with the k20, cams for those really don't...

You forgot headwork. Probably the MOST IMPORTANT thing by far that wasn't even listed there. Headwork is probably the only thing holding this motor back from making real power.

Did i see they quoted 6 hp 8 tq gain from this intake? That's pathetic. They're really selling themselves short trying to sell it without requiring flashpro. I guarantee the gains with flashpro would be upwards of double their figures quoted. There's been tons of people that have tried to...

It absolutely won't act right without flashpro. Changing pipe diameter on a MAF setup is a big no no. You'd be lucky for it to not completely stall out.

I've seen someone work already for some drop in camshafts, so i hope you work on them for a while, he ONLY picked up power for 400 rpms from 7000 to 7500 (7000 to 7100 it only picked up like 1 or 2 hp, but 7100-7500 it picked up 8-10 hp) Everywhere else it either made less or lost horsepower...

I wouldn't say anything is wrong with the PRL. But i had a hand in the hybrid racing cai. It's one of the most epic pieces out there for this vehicle. It was designed from the start to beat every intake on the market, and Russ went on to do dyno comparisons to prove just that. Not to mention...

It sets it to 7600, same as the TSX flashpro for the k24a2 engine.
