First time at the track with the new mods -Dallas Performance hand ported snout
-Dallas Performance hand ported LSA heads
-10" lower
-air raid intake
-ID850 fuel injectors
Car made 610/590 in 105 degree dyno room through the auto. Ran of a best of
60ft--- 1.69
330ft-- 4.77
1/8 ET- 7.31
1/8 mph- 97.80
DA was TERRIBLE at 3479!
Honestly felt like the car had a 7.0-7.1 in it at 100mph but didnt get there. Needs help with the 60ft and headers/midpipe/heat exchanger should help a good bit. Could use some advice though, I'm leaving off idle and just flooring it, car is not spinning at all but isnt cutting great short times, what can I do to improve this? Gears/Converter?
Also what do you think my next round of mods will yield?
-Heat exchanger
-headers w/off road Xpipe
-considering an Ice box in the trunk

A 1.69 isn't a good short time?
A converter would probably net you the best improvement in short times with a heavy car like that. I'd personally leave the gears alone.
The other mods you mentioned should put you well within the desired range. It's already making beastly HP with awful ambient conditions.

For a car that puts out 610 hp at the wheels, that doesn't sound that great, but then again it is pretty heavy and IRS, so guess it's respectable. Put that same package in something with a good suspension for launches and I could see ~1.5 sec 60 ft's or better...Not saying you'll get that with the V, but for reference...Even in my stock Syclone I would get 1.7 and the vr-4 probably at 1.6 with ~330 at all wheels. Granted those are both AWD, but not near the power.
What gear ratio does the V2 come with, anyhow?
A higher stall would certainly help, but keep it reasonable and matched to your cam and powerband too and if you do go there, put som additional cooler(s), as they create a lot more heat from slippage.
Anyway, not sure what those 1/8 times equate to in 1/4, but bet the car pulls nice once it gets going!

Yeah, those are some strong times then and if you can get in the 1.5x's, that would be awesome. Have you thought about air bag in the passenger coil for preload? Be pretty impressive if you get that with IRS, for sure and the car sounds like a beast.
Back in my chevelle days, guys in the high 10's were cutting 1.4 times (a-body has a good setup when it's upgraded and dialed in), so I could see it being mid 1.5, low 1.6, which is still a hard lauch. I'd like to see what kind of 60' I can get in my vr-4 after I get this round done, as it'll be putting out some more power. That gives me a frame of reference then on how strong yours must pull then, as mine may be a low 12 second with a 1.6 and wow for it to pull in another second + as it's accelerating. (galant pulls hard too
)

Yea, with 600+ HP, mid 1.5 60s should be possible. Maybe u need suspension work? A stall would help too. My buddys stock suspension, full weight, stock wheels, cam only gto runs 1.65 short times, and he has about 400whp.

)I'm considering doing a gears/converter later. But the car should be making 650+ hp soon so I'll go take another swing at the track then.
