Default Help. I need 20hp. What else could I add?

I put down 332RWHP and 342RWTQ. I'm not real happy but these numbers are good. My goal is to have a 350-360RWHP, Bolt-on car w/nitrous. I'm not stopping untill I get 350@wheels with Bolt-ons.

I could use a little help on deciding what I need to do to get 350@ wheels. My mods are in my sig.

My timing was about 21'-22' on average. At it's highest it was only 25 and as low as 19.

The only thing I can think of is:
Power Pullies.
More Timing.

What else is there??

How about a cut-out. Just make sure you don't go too high with the timing with nitrous or <img border="0" alt="[kaboom]" title="" src="graemlins/gr_bomb.gif" /> .

I guess you could go with a light weight fly wheel and a carbon fiber drive shaft but I doubt that would boost your hp up very much.(not really sure at all on #'s).

U/D pullies would be a solid 8-10 rwhp and a cutout is another 10. THats your 20 <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> if you want a few more you could try an SLP 85mm MAF..every little bit helps.

I have a 3" Y into a single 3.5". I don't think a cut out would help. I have tried the SLP 85mm MAF. I really liked it, but now I have the NX MAF System. It's probably not better than the SLP MAF, but it's a awsome nitrous setup.

Thanks.

Any other ideas??????????

Hmm... only things i can think of are the free mods, TB bypass.. a 160 degree thermo, hpp3 (for the fan settings, and maybe tuning when not using the N20)... How about a ported TB? i hear of those adding anywhere from 3-9rwhp. All of these together may not get you 20rwhp, but it will at least get you closer.

Edit: sorry didnt see you already had a ported TB

-Remove filter
-Dyno tuning with a wideband O2 sensor
-What size Y-pipe are you running? And it goes into what? I would run a 3 into 4" into a 4" I-pipe back to a 4" cuttout.
-Cuttout
-Timing advance, you'll be better off with about 27-28 degrees of it. Get rid of ALL knock retard. Use a 4.7k ohm resistor in the IAT sensor harness. Use a 160 degree thermostat with appropriate fan settings. Kill your cats! Cats are one of the leading causes of pinging. If all else fails and you still have false KR you can use a KO box made by NineBall. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />
-Fernco coupler mod (tube between the MAF and TB) or SLP coupler.
-Ensure that your ported TB is opening %100 when your foot hits the floor (takes two people to truly test.) Knife edge the blade and epoxy mod the IAC and PCV holes (MTI doesn't do these things.)
-Port and decreen your MAF. Correct the mixture back with your MAFT.
-Index the plugs. It's a PITA but it's worth a couple of ponies.
-Short belt mod. This bypasses the AC and power steering.
-Underdrive crankshaft and alternator pullys.
-Redline synthetics from the rearend to the engine.

That should get you started! <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

Just noticed this comment...

"I have a 3" Y into a single 3.5". I don't think a cut out would help."

Why do you think a cuttout wouldn't help? You're running a splitflow muffler (which I'm not familiar with) so unless it is of a bullet type design I can assure you that you will gain from a cuttout.

Got any pics or know where I can see the NX MAF system?

LOL! No, I was just curious to if that MAF might be somewhat of a restriction. If I ever spray the '00 Z again it'll be with a direct port and will be in the pursuit of 7s. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

Even if removing the filter does add power is it worth it. Its like running a 500 shop of nitrous. Sure it will add power but you could wreck your motor. Go Coronel GO!!! <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

1.8 roller rockers, its kinda a bolt on but its kinda not. but its more of a bolt on. Since you have the sealed ram air you could already be at you 350 goal and not know it, cant measure ram air on the dyno ulness you have a fan that hooks up to the speedo and increases air in realtion to the speed. or get the loudmouth cat back, thats a lot of power off of just a cat back. Or you can forget all that, dont put anymore parts on your can and get custom tunning and that should be 20 with no problem. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

COLONEL:

The NX MAF actually has better flow caharachteristics that a factory MAF ends. They are much narrower and smoother....by a long shot.

Hey Steve get pullies, port the NX MAF a little, buy in on Ryan's LS1 edit! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Have you done the WOT mod yet?
More timing, on Edit mine showed 27 at the high RPMs.

About removing the filter...

True, you could suck something into the engine that could damage it. To minimize this damage you can do the 'ole pantyhose mod on the lid or you can simply "de-filter" a stock paper filter leaving the screen in place. You'll have the flow of no filter at all while limiting the size of particles to what would be fairly safe to run at the track. Sure, dust and very small bugs could still enter but if it's worth a tenth in the 1/4 then the small risk of a slightly shorter lived engine may be worth it to you.

Strange things can happen on dynos or at the track but I can tell you that I consistantly pick up a mph or two (depending on which car I'm running) without the filter in place. It may compliment the !filter mod in the fact that I'm running a FTRA.

Hey Colonel, how do you like the FTRA? I have one and I can't see how it would hurt, but some people don't think they do anything. With just a lid, filter and FTRA I dropped 4-5 tenths at the track, so I think it helped. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
