Yeah, your numbers are ridiculous!
Ehh, I gotta bring my MREV2 and spacer to RT for a Cosworth/MD Comparo. Most likely, I'll be getting rid of my Cosworth, but DAMN it looks good in the engine bay. Vince said the MD exhaust depressed the low end a little, but above 5500rpm it opened everything up.
With the MD equipment in, Vince will do the final tune. Reading up on your Cosworth thread, I might even switch back to the stock 06 airbox based on Tony's assessment of it. Will lose the sound, but gain as long as I keep the filter clean.
With all those parts back on, I'm hoping Vince will be able to make this thing scream past 7k. Once that tune is set, he'll work on my nitrous map and I'll be good to go.
I'm hoping to get SAE numbers around 300whp/270wtq and then somewhere around 360-370whp/400wtq with the N20 (75-100 shot ZEX kit)
I'm hoping I can wrap this so I can put my kit on and let this bad boy scream down the open road. If SG/Carbotron comes out with something that beats the MD, that would be the final touch and then I have to leave this addiction alone.

Little update since the car is still in the shop and I am overseas.
The drag strip was lots of fun but my times were terrible. I was only able to get two runs in before my clutch ran into some issues, so I didn't want to completely blow it and not be able to drive home. The event was lots of fun, despite the issue and times, but the numbers look very promising for the next time. I just got to get a few more practice runs in and should have something respectable. Also need to get a new clutch as well. I was set on getting the OS Giken per Adam's recommendation, but it seems 03threefiftyz has had some issues at the drag with his. Gotta do a little more research on this.
Right before the strip, I drove down to Motordyne to pick up a set of his Nova axlebacks and I must say that it is amazingly quiet compared to the Gamma. Since it was right before the drag and as part of the prep we ran the car on the dyno and we didn't notice any power lost at all. Not that I'm not satisfied with the Nova, but I was talking to Tony the other day and will be getting a set of the V2s as well. I'm really piling up on the MD stuff....
As far as the engine goes, it runs reasonably well and hasn't had any major issues yet other than its insane need for oil, around a quart for every 1k miles. Zcar will be running some test to see what's going on with this. Also a couple more things that we will be looking into
-install the 3" maf with Apexi
-maybe install new VTC
-tuning the get rid of the very low power right before 3k
-install a new clutch
-slight idling problem where the rev would jump around to find idle
-some misc tuning
Once I get back I really need to get some good vids of the car. If all goes right then I might be going to the track with Zcar and will definitely get someone to get some vids there.
