10.9 is a goal of mine with the V, and I'm curious if any one has a ball park of what HP # it would take to do it. No weight reduction, and yes I know an 8.8 or 9' is instore.

Also I know of the many factors involved, altitude, tires etc etc
I guess Im looking for who has actually hit the 10's in a V1 and what it took.

Minimum of 700 I'd say...

wheel or engine?

To get in the 10's i'd say a solid rear axle would be a better choice than an upgraded IRS. Wheelhop will kill the 60ft times needed to make those ET's.

has anyone put a solid axle in a V1?
and I just googled a HP+weight=ET calculator and at 4000 pounds it said 610 HP. In a perfect world.

Wheel...

And the 8.8 isn't bad. Wheelhops a bit still but I'm sure a BMR wheelhop bar and bushings would fix that. Much less wheel hop than stock either way! Solid axel is great for the track but the IRS allows the car to keep a nice ride and good handling

Considering this isn't a perfect world... I'd say closer to what I said. Given these cars have a hard time getting out of the hole, you'll need the extra power/torque.

My car making 550 ran a best of 11.8 on street tires when my buddy ran it. That was with a shitty 60 foot because it was prior to the built rear. With the 8.8 rear and some good tires, should go 11.5 now.

what does your car put down before the spray? also what size shot are you running to hit 550? and I see you have the 4.10's outback which will def help lower ET

NeverSatisfied02

N/A it made 430. After tuning it on the conservative side and pulling some timing for the nitrous, it makes 418 n/a. I'm running a 150 shot.

It's been done, but I wouldn't attempt it. As mentioned above it would really hurt the car's overall handling and ride quality. I think there was a guy who did an LS7 swap with a solid rear conversion a couple years ago. Don't know where the car is now..

SRA> any IRS in the V. Witht he right suspension the SRA might suprise you with ride quality. I say with some weight out of the car, a SRA, and 550rwhp it could go 10s on a great pass. But is it worth the money?

NeverSatisfied02

iTrader: (12)

Hmm... Makes me wanna strip mine for a trip to the track just to see if I can get a pass in the 10's! Lol it would have to have some ridiculous tires and about a 1.5 60 foot to do it though.

I think with some ported 243's, 1.7 rockers, fast intake, bigger TB, 160* stat, UD pulley and a retune, my car should make around 470rwhp n/a. I'd spend the money on some nice AFR's or trickflows but I'm pretty sure gains over the stage 2.5 243's will be minimal for the price. The 150 shot on that will put me over 600rwhp. I'd almost be tempted to go with a 175 shot which is the max my current NX kit will go but I don't wanna blow it up... YET. Lol

Only other thing i'd need is a driveshaft cause I doubt the stock one will hold up with that power and some sticky tires.

OP, everyone is right. To get into the 10s, with out any real risk, you will need a SRA. There are guys here with 600+ whp, and they are in the mid 11s. Its trying to get this pig off the line that kills are ETs. And I have never seen anyone put a SRA in a V1. But the real question is, like itsslow98 said, will in be worth the amount of money required to get in there? I would love to see someone put an SRA in a V1. But I never will, because I am not spending another dime for mods on my car, haha. Since there is none (that I know of) that have done it, you will more then likely be be looking at easily $10,000+ to put a built SRA in there.


Taylor, what is your Fuel System like? If you are still running the stock one, I would look into a boost-a-pump or a new intake pump. Especially if you really plan on doing all of what you listed, the stock one will be maxed and you will not see the real power potential of those mods plus the 175 shot of happy gas.

A V2 will run 10's with the stock IRS...with no mods. Has anyone looked at the real difference between the V1 and V2 rear sub-frame assemblies?

ColeGraham

iTrader: (8)

the difference is that GMPD decided to sit down and design the V2 properly...

the V1 design session probably consisted of the following...

Engineer 1: "We need to make the CTS faster. What can we do?"
Engineer 2: "Not sure...lets see..."
Engineer 3: "We got a bunch a LS6s and T56s laying around in Bowling Green...lets stick that in there."
Engineer 2: "What about the rest of the car? Will it fit? Will have have to adjust anything else?"
Engineer 1: "Those are good questions."
Engineer 3: "I GOT IT! Soltice Differential and new plastic molds! **** it, were done, lets go have a glass of wine and some crackers."
Engineer 1 and 2: "Lets...job well done team."

DMM

Haha Cole...probably a fair account of what actually went down. I am interested in 10's also but think the 8.8 kit with poly rear frame mounts and softer rear shock valving would be the way to go over f'ing with an SRA install. I think a V1 in the 10's would be awesome...everyone knows what a V2 can do and us V1 guys are looked down on for it IMO.

Just wish I had time to get in the damn shop now.

LOL @ ur engineering discussion post. haha

Fuel system is stock at the moment. That the other reason why i dont plan to go any bigger with the shot until later and even then, it will only be a 175. Right now, the A/F is straight across at a consistent 11.4 my buddy said so its not stressing at what its making. To make more, ill need a minimum of a boost a pump if not a bigger fuel system all together.

ichpen

That's a fair question. There's a lot of heavily modded V1s that will spank V2s from a roll so I'm curious if it's rear track/rubber/gearing etc issues that prevent the V1 from getting those numbers. IRS differences aside.

.Houdini.

I know we have a handful of owners that have pretty stout V1s and have done the geforce rear or cs 8.8 upgrade. Why have we not seen time slips on these? Surely a few of them have gone to the strip. What is the hold up? It's been long enough already.

NeverSatisfied02

iTrader: (12)

Pretty sure the madman rear is a solid axel setup right? For just $6k you can have it. lol

My 8.8 should hold up just fine. Not planning on making 1000hp with this thing.
