Autotransabori

Change to a automatic transmission and remove the torque converter and replace with a cluch and u will run 9's my name is Adrian Sabori I drove the white JG Edelbrock civic

**** why didn't i think of that

Ok guys, I have a update. Had the car at the track last night. The quickest pass of the night was 10.5@135. Although the short track was lacking a little more then usual due to a worn out set of slicks. Even though I upped the limiter it would not trap any higher. I upped the limiter in all gears to 9100. And 9500 in 4th. Even with the limiter raised in 4th it only trapped 1 mph more then when I shifted at 8600 in all gears and hit the limiter quite a bit before the finish line. After looking at the logs I can see "and could feel" the car just doesn't make enough power that high in the rpm range to trap any higher then that.on the logs while looking at the mph you can actually see where the car starts loosing power because it isn't increasing mph quickly

So now all you h guys that are making power up to 9500 what mods are most worth while? Degree the cams to shift the power higher? Different cams? Intake manifold? Anti damper or fluidamper?

you SERIOUSLY need to get aftermarket valves. 90 lbs of seat pressure is way too much for the stock valves.

Stock intake manifold
Stock tb

on my pump gas street car just adding a junk2 manifold and 70mm throttle moved the powerband up. try a larger plenum intake manifold and larger bore tb

As far as I know, those Skunk2 Pro series valve springs are only rated at 50psi, as per Skunk2. Now, I have never measured them either.

EDIT: Valve Springs - thanks Rick

VALVE SPRINGS!!!!!!!

Sorry, thanks, that is what I meant. For some reason have valves on the brain today.

Well I am pulling the head, it has been on there for a long time And it was starting to push coolant. I am atleast upgrading to ferrea valve springs, valves and keepers. But that still isn't going to help me carry power out or will it? I need more ideas of how to get it to carry out to 9500. While keeping on some what of a budget. I have never had to make a setup be so precise. But with this crappy gearing I have to. Anyone want to trade a ppg 4.4 for a 4.2? H dogbox

Can cam gear adjustments move the power up in the rpm range that much?

nonvtecallmotor

Sounds like its floating the valves at hi RPM. That is whats causing you to have no power up top. Cam gear adjustments can move power band around

tofast4uh22

It doesn't stop accelerating, it just doesn't halve nearly as much power. I know that distinct sound you get when the valves float. I didn't hear that.

tofast4uh22

So what are the necessary components to get it to carry the power out to 9500.
Cam gear adjustments, good intake manifold, tb, valves and proper valve springs?

tofast4uh22

Anyone know if I can use ferrea valve springs. And still use my skunk2 pro bases and retainers? Could I use the ferrea locks with all of this?

snobordboy

Can't comment on that as I am still using all Skunk2 springs retainers etc with Ferrea valves, but some better valves and a good valve job should help out.

I am amazed that you made so much power on a stock IM and TB, you are pushing a lot of air through that little TB, and a pretty restrictive manifold.

Once you have the head done, get your valve clearances laid out well, so that you know what range you can safely test through, and try out different settings for the upper end power.

Or what's everyone think of skunk2's new pro series hp springs. They are rated for 93 pounds of pressure. It would be cheaper to upgrade just the springs. But I don't want it to be at the cost of a motor.

IMO I would think its not breathing strong up top after you build the head upgrade to a better intake manifold/ tb and also that turbo housing size your running would also be a playing part in being restrictive too.

my builder from my old race motor neglected to install the H spring seat adapters. My engine made power to 9200 (NA) yet, the markings on my cams and finding out the seat pressure I was running was a quick realization that I had lost control of the valves that high.

with the adapters you should be around 60lbs, but running some heavy stock valves isn't going to help your situation.

the intake manifold/TB is really hurting you up top. you'd be doing yourself a big favor even just cutting the IAB webbing out and porting. Personally, with the amount of power you are making, i'd start with the intake/tb before I went and spent 1200+ on GOOD head work.

Rosko makes a pretty sweet manifold and plenum setup too. might be worth checking out.

I am going with a golden eagle intake manifold, bloc 76mm tb. Ferrea 6000 valves and skunk 2's new 93 pound springs.

Does anyone think I would be better off with golden eagles 6" plenum?

98vtec

nearly anything will be better than what you have now. I don't remember the actual size, but Rogers BMC was friggin huge!

the bigger plenum is only going to keep that air flowing!

That all sounds good, but why the Golden Eagle manifold?

tofast4uh22

Desmond that's what I thought. And that's why never got a manifold before because I didn't believe in the golden eagle. The skunk 2 has too long of runners and too small of plenum. But now after researching the specs on the golden eagle it should perform real well. There are not many h manifolds available

tofast4uh22

It has a decent size plenum especially the 6" plenum and the runners are pretty short so it should carry tq out pretty far. I never really looked too much into it but the stock h manifold has roughly 15" runners. No wonder the tq falls on it's face.

98vtec

typically gut it out and cut the runners down.

I only ask casue If your going to spend the money do it right one time with something worth while. Here is the great manifold I would jump on for the H series motor. Manifold will need to be port matched to whatever tb size your looking to run, but that's it. http://www.xcessivemanufacturing.com...pid=234&step=4
