In all reality, I know next to nothing, I just get lucky a lot, and I surround myself with smart people. Can't complain though lol, it seems to be working.mechanicalmoron wrote:Don't take me seriously, you obviously know way better, but.....
This would look a bit funny, but you could put a pretty big scoop over that airbox on the hood, face off the fender side of the box, and make it large enough that you could put two of the stock style filters side by side diagonally, and if you think that wouldn't stop enough water if it rained or something, a further catch or second filter in the airbox.
If you faced off the back of the airbox you might even get a ram-air effect. But maybe it'd get too wet or something.
As far as hood holes, you just need a ramp shaped part on the rear side, such that you could drive a toy car out of the engine bay through the hole, and strait up towards the windshield. (didn't see a picture of this hole)
It's a race car, cut them funky vents......

Give Broc and internet high-5 for me.
Sure we can do that, but I pick the location. Hmm, where is E85 not available?..FlatBlackIan wrote: I can't wait to get it on the Dyno after OFR to find out for real.
Dave, are you ready to duke it out for highest HP NA KA on pump gas? E85 comes from a pump right?
You basically go by what the MAF is known to max out at (so like an N62 300zx TT MAF maxes out around 530whp @ 5 volts). From there you just use a ratio of voltage to horsepower. @ 3 volts you should be about 318 to the wheels. Its rough, but not bad.Razi wrote:Pretty impressive that you're maxing them out on an N/A setup.
I was hitting 93% at 6200 RPM with my 370ccs, that convinced me to switch to a bigger size.
Smurf, how do you calculate rough HP with MAF readings? Do you put in the MAF size + the voltage reading to get a rough estimate?

AFR's are in the 13s until 4500 then I pulled it down to the mid 12s. Conservative is the name of the game. I am still also reletively light on timing in the top end. Once it gets a big boy tune, I fear the injectors will be too small.PapaSmurf2k3 wrote:This is awesome.
I was going to say "well, you can calculate rough HP based on your MAF", and then I remembered what thread I was reading.
What do your AFRs look like?
You could always add an additional injector of your fuel choice (methanol perhaps? Although I doubt you need it) to just after the filter, sort of a "throttle body injection" type setup, you know, if you had a throttle there. Trigger it to come on only above 4,000 RPM or something, otherwise airflow wouldn't be high enough to sustain turbulence/atomization. Even though you don't have the throttle plate located there, it should still work.
What fuel pressure are you running? You could try bumping that up a little bit too just to squeak by.
What did you switch to? I never thought the 565s would be too small, so I haven't looked at much else.Razi wrote:Pretty impressive that you're maxing them out on an N/A setup.

If I am towing the car, then nowhere lol. Too bad you will win the driveability challenge. For some reason giant throttle bodies, and tons of compression do not lend themselves to streetability. The step from no throttle to part throttle is huge.Ajax wrote:

Are you controlling it with megasquirt? Or somethin' more fancy-like?

Nothing, just adjusted the throttle stop screw. Its really really cranky when cold, and someone has to sit in the car for a minute or two to keep it running. This isn't really an issue though, because its not a daily driver.NismoZRS wrote:Hey, i have a question for you.. What did you do to have idle air?? i'm in the middle of building itb's and i haven't found a good way to create idle air yet..
Edit: I'm also not going the route of map sensor or megasquirt.. I'm building an airbox plenum that in inducted from a MAF and filter intake.. and tuned with SAFC 2
