H/c/I, intake and inject question.

[Diabolic]

Whats you guys Rwhp estimate?

275 only because the camshaft is a tad small, and the compression is below 10:1. You could actually see more. Small cubes need RPM to make bigger numbers. More cubes need less RPM.

7.9@87mph with your good driving and decent traction. 1.7ish 60' time

Fixed.

I'll be happy with 7.60s and as long as it makes 300 rwhp il be all grins.

My stock gt40s and e303 put down 267/304 granted there will be much more power under the curve with those heads but your crazy to think he is only going to get 275 out of those brodix heads.

Chassis is getting attention too.

Like I said maybe more. It's all about the combination. I personally feel the camshaft will hald him back a little. How does the flow of those Brodix heads compare to the flow of 170TW heads or AFR 165's. Actually the 170's would be better compared to the 185's, but they can be used without flycutting the pistons so I included them. I had the Lunati cam 51014(same specs basically), with Fox Lake ported TW170's, Systemax intake port matched, 70mm tb, 30# injectors, Pro-M 75mm MAF meter, and 1-5/8 Longtubes in my 89 Hatch. I put down 312 to the tires at Murillo Motorsports in San ANtonio. He told me the camshaft was really holding me back. It was done pulling by 5500 RPM. I also think that 1-3/4 Longtubes with a custom cam would net him an additional 20+rwhp. He seems to drive the piss out of that thing so who knows, he may just get that 7.6 if the weight is under 2900. Mph will tell the hp.

Hmmm, well I just figured that adding the additional fuel in the tune and keeping the stock fp was far better than asking an injector meant to flow at 39 PSI to bump up to 70+#'s. I have the knowledge to do it the right way. The way I do it is the right way. I know guys that make 400+hp on 19# injectors and a 12:1 FMU, but that certianly doesn't make it the right way.

If you're really running 30 pound injectors without a proper tune on ECM then you are probably washing down the cylinder walls with gas, which is bad. The fuel pressure at idle is part of the equation, but you can't adjust pulse frequency and width through a fuel pressure regulator, and that is much more important than pressure at idle. Only the computer can compensate for those parameters.

Well, I hate to have to tell you this, but those 30's that you're running, they're getting the same treatment on a dry shot of nitrous just as the 19's I was using, and any other size injector that is used with a dry shot of nitrous. Those dry kit systems work the same way regardless of the injector size. They all get hammered, just because one is capable of distributing "xx" amount of fuel doesn't mean they aren't subject to the way the nitrous system is designed to work. If you think the fuel pressure on those 30 pound injectors isn't jacked sky high when you flip that switch you're mistaken.

You say you have the knowledge to it the right way, and that you are doing it the right way, but that's subject to opinion.

They flow really close to an afr 165.

The cam is the bottleneck so to say, I just want to see how it runs with it. If I feel like I can get another 15-20rwhp from another cam, then I'll do it later on.

I was wanting to degree the cam, but am clueless on where to start on getting it correct.

What made you decide on slicks?

[91CoupeMike]

Or drag radials, I'm still on the hunt for some 26x9 or similar. Slicks work and I dont mind swapping tires at the track.

I live 5-7 miles from northstar so the hike isn't but a skip.

I got a 1.82 60ft with old dry 26x10.5, stock power and suspension.

So hopefully the new set up well get out of the hole better.

Without the proper tools, you can't degree it, unless you just get lucky.

Personally I wouldn't get into the slicks unless you have a really steep rear gear with that combination. You're going to bog like crazy out of the hole with slicks on. I don't think you'll be making enough power to bother with them, but that is just my opinion.

[91CoupeMike]

In a nutshell what advantages are typically found with a properly degreed cam vs a dot to dot instal?

3.73 with 2.95 1st gear.

That's why I want a smaller slick, so it will have a higher tendancy to slip a little.

Mike you are going to degree the cam to make sure specs are all on point when you install it even though i have the cam card for you degreed and measured at every point of the lobes. This cam will be installed dot to dot. they grind advance in the cam

If Anderson reccomends dot to dot then I won't worry with degreeing the cam.
