200+ WHP?

[PCGUY112887]

Not to thread hijack, but would a fender well intake be better than the stock airbox? One thing I have noticed with the cone filter is that it murdered my gas mileage and I'm either going to run it into the fender or put the stock box back in.

Fender is the best way to go... next to stock air box with K&N dropin. Your MPG may jump around some when you change up your intake, as it takes the car some time to relearn values before you get accurate MPG ratings.

I also had no idea that BHP did not equal WHP... I thought that is how much power you had "at the brakes" so it was the same as WHP... just figured it was a region difference since the only time I see BHP is on foreign things.

ohhhh learn something new everyday. i didnt think there was an acual term for that other than hp at the crank lol

What gain can be realized from just porting the intakes and going to headers? I am thinking that head work and a cam might have to wait for a while yet...

a decent amount from what I've heard. headers are good for 20hp then ported intakes maybe 5hp and better throttle response.

Not the same thing at all. BHP is measured at the crank. That is, with the engine directly connected to a dyno. Wheel horsepower is measured at the wheels on a chassis dyno. The difference is the loss through the remainder of the drivetrain.

isnt bhp the same as whp? thats what i always assumed

Totally agree... I thought I would be outflowing my air box because the opening is only in the very front of it and it's just a little slot, but I drilled holes in my airbox to test and my MAF showed that I was drawing in no extra air, just warmer air. I need a new air box bottom I use a K&N dropin however.

You will not get 260 WHP that way. Need to at least add headers/full open exhaust to that list.

I wasn't talking about wheel horsepower, notice BHP, brake horse power.

"redbird"s 3400 is a stock 90K bottom end, 1617 grind cam from the WOT-Tech store, some ported heads from me and some tuning is 224 WHP although it's a 5 speed. He's had a few problems recently but he drives the crap out of it.

to get 200 WHP you need to shoot for about 260 crank HP. A 3500 top end, good cam and 3500 exhaust manifolds with a good tune will do that easy.

so basically a cam and a tune will get 260 BHP in a 3500!? seems a bit optimistic

The snorkel on my stock box was about 1.5" opening, way less than the stock TB.. hahah. I opened up some parts on it, but it draws from fender air too so not really hot air there.

For the K&N only use a drop in filter. These engines do NOT like cones, and tend to lose torque by using a cone filter. The stock airbox (at least in the w-body) is really well designed, and is not as restrictive and most people think.

I fired up a 2.8L and it ran great after sitting in my parents barn for 2.5 years before I installed it in a friend's truck.

I need to save up some money... how long can an engine sit on a garage floor?
