Backfire when shifting

[canu_50]

I don't know the engine enough to believe it could do such high number. I would of figured out with out cams just bolt on and tune should be around 200-210 whp max!

I will be putting it to the test N/A then Turbo. This is what we do at our shop! We did the same with the EVO X when it came out!

I cant say for sure it will, but with my experiences with B18 and K20/24 motors, is that anything is possible with enough attention to boltons combination, fuel delivery, compression, and tuning skills.

My personal COMPLEYLEY OEM B18C block'ed motor setup puts down 240whp, shooting for 250whp before winter with slightly larger injectors and TB / intake manifold molestation.

Will that show true maximum gains and fuel efficient? No. Will it destroy your motor? No. Additionally if you were intelligent, you know know that an intake would never cause enough change to damage a motor from a car with an extremely conservative tune oem.

I've driven plenty of exotic cars that do this off the dealer lot many times more often that a more standard general public automobile. All cars backfire, all the time, constantly. Some naturally, some due to bad tunes. There can be at least 1000's of reasons why a car will fart.

Why don't you post up your motor builds and tuning experiences mr. drift. Lets see your impressive background.

Yep seems like you have something to prove. I've done builds I had everything from a wrx, STI and an evo x. I'm not a "tuner" like you lol but hmmmm all the tuners that I've been too always says an intake can really do some damage specially if the car is running rich and a common symptom of running rich are backfiresbetween shifts. the OP never posted his Afrs so we dnt know what his running but hey he had backfires after installing the intake. So guess what maybe a tune will help the op's ride to run smoothly. Again I would not say his backfires is a sound of awesomeness. Till he gets a tune. So go back to the Honda forums mr tuner

Was the AFR under spec? Was it posted?

No it wasn't, and an intake alone will not throw off AFR by much at all. Again, how is this going to hurt an engine? I want to hear your explanation of this.

It will not harm the engine right away, but Over time as per all the tuners that I've been too rich fuel/air mixture will cause excess fuel to "wash" down the cylinder walls and cause ring wear.

An intake will not ever make an engine run rich enough to ever ever ever cause ring wash. I have nothing to prove, your just talking bullshit and extremes that arent true. The op isn't appreciating anything your saying so why you here? Something to prove? cus so far your proving you don't really know what your talking about.

I fully believe with oem internals, Minus cams and maybe valve springs.... that this car NA could make 250-280 wheel.

And your a reputable tuner and know what your talking about!

Yup go back to the Honda forums. lol everyone can build but will it hold? 250-280 wheel with an full exhaust and intake plus tune lol probably on your make believe dyno.

And you are right for a lot of newer car with turbo! Our evo x we had tune it after the intake install. But on these i really don't think especially that more air flow means running leaner and not richer unless the ecu overcompensated.

Canu 50, you contacted Injen yet?

I have always been told exhaust before intake if your going to suck more air in it has too have somewhere to go to much negative pressure could be the cause not sure just throwing it out there please correct me if I'm wrong
