Well I have 225 R-compounds now, they're not too bad. Like I said, it is getting a bit cold and I only have gotten on the car at night. I think with sub 70's traction wouldn't be an issue.
I am going to run the MT Drag Radials eventually for the track and/or racing. An when I get my 6UL's I will roll on R888's 225/45/50's

I disagree, I would make 460+ on the same dyno as him. On the road course, yeah he would. On the street, highway pulls...I don't think so. I make over 100 hp more than him peak, on the same dyno of course. Look at high horsepower Supra's, Evos, Civics they all my graphs like mine, and they're all extremely fast on the track, you do not drop much RPM when you're drag racing.

I am not so sure. I am willing to bet that if he were to do a pull to 8500, which would be more realistic with the cam he is running, the torque and horsepower curve would begin to look like Sav's. The only difference is that it has shifted.
My cam is only 237* advertised duration, with 214* at .050, and I turn 8000! He could easily turn much higher RPMs, and get much more power.

And I am going too, it was just to get my car tuned. I don't want to do anything crazy just yet. I will be revving my car to at least 8K next season. My curve would look similar to Savs just moved to the right 2,000 RPM. If I revved to 8,500 I bet I could break 500 whp on a dynojet @ 20 pounds of boost.

I have Supertech springs, Ti retainers, Ferrera Valves. I have no idea if I have shim under lifters? What do they look like and I might be able to tell you.

Would have, could have, should have, etc.....all I see is a plot to 7K. If you're tuned to utilize the cams, have the right gearing and everything else in order then sure, but I'm just looking at what I have seen so far.
What's being said is that until you tune it this way, then you're giving up a lot of area under the curve.

I went to 7,500 made 425 whp and it was still climbing, that graph I showed went to 7,000. Either way, on a dynojet, or similar I would make a lot more power (Put it this way, there was a guy in the shop made 700 whp on SP's Mustang dyno, and peg'd 800+ on a dynopak the same day) It isn't fair to base it off of two totally different dynos and make a graph. My curve is totally different then his, and I would need more RPM to make mine look similar. Our cars are built for two totally different things, I am more into drag racing....he is a road racer, so our parts, curves, tunes etc. are going to be totally different, Sav's are is a beast and my next project is going to be a time attack Miata so I will have to follow up with him on how to make that possible.
Put me on a dynopak, with the same tune same rev limiter and I will break 460 whp at 18 psi...basically is all I am saying. Sav's car is beast and this isn't a pissing match. I love you all xoxox thanks.

No pissing match here, either. Just pointing out that you're leaving a lot on the table as is. I'd much rather see you put that money into intake manifold experimentation or a set of custom cams and pick up a huge amount of power under the curve vs. a $6000 ECU setup so you can have the convenience of running pump gas.

Something that always bugs me about comparing dyno graphs is that dynos and their operators can produce variable results. I think that comparing charts from different dynos is not necessarily that useful for that reason. What I'm saying is that the comparative analysis across different dynos should not necessarily be used as the basis for definitive conclusions.
One element of disparity that I'm suprised neither Savington or jtothawhat mentioned is that Savington's chart is from a 1.8 and jtothawhat is a 1.6. Regardless of power under the curve, jtothawhat is a pretty damn efficient setup.
Mr J can you please post a link or pic of your current engine bay?

but like others have said, power under the curve in YOUR power range wouldn't help him at the drag track at all. if he runs a 8500 rpm redline, spending time and $$$ making power from 4-6k would be stupid as he would never be under 6k down the 1/4 mile or launching.
