1000 miles and went to the track!

[c5racr1]

got 1000 miles as I went through the track Gates. my car is a GXP A6, mods are nea otr filter, stock tune with TM turned off.

no cool down 1st pass
13.30et
105.56 mph
2.056 60ft

slight cool down 2nd pass

13.16 et
106.64 mph
2.030 60 ft

cool down 3rd pass

13.26 et
105.54 mph
2.054 60ft

i messed this one up, at the line. long story :)

all runs were somewhat hot on the IAT cause the staging lanes were long and the MAF would heat soak.

all and all i am happy

next mods are

LS7 crate motor, had it from a previous project, FTI 3600 stall, Kooks long tubes, and corsa GXP exhaust (with cats)
my guess is 11.30s at around 118-120mph, we will see!:woohoo:

I'm still waiting for one to break the 12s in stock form, that of course will probably take a sub-2 second 60ft.

Times look good, were you launching off idle or stalled? How was your overall traction?

Welcome C5! Good runs!

[G8GXP4now]

Good times. Did you lower the tire pressure?

Seems like overkill to buy a GXP and then pull the motor, but she will we a beast when the LS7 is dropped in.

I agree but he/she will sell the ls3 to one of us cheap

Holy shit dude! That's pretty damn sick (as in good) for a near stock GXP. Nice runs!

Is the ls7 bone stock? Are you performing the swap or paying a shop to do it?

CAI/tuned LS3s are in the same ballpark hp when comparing to LS7s, granted the 505hp was an estimate due to each motors hp varying to a certain degree due to them being hand built, and tolerance differentiations. Seems like a tall order to pay someone to swap a motor that is producing similar power.

Granted the starting hp IS higher, but from Tech and other places, I've read the LS7 block has its limitations, which is why many ZO6 owners, and people building up LS7s use a LSx/ Warhawk block. More so, it appears the aftermarket seems to be producing more LS3 parts regarding stroker kits and FI kits. Heads/cam choices are one in the same for the LS7 and LS3 so that's not comparable. Just my $.02 on the matter, I'm not knocking your idea, I would actually love to see a G8 with and LS7, but from a cost perspective (if you're indeed paying somebody) it doesn't line up for me in a GXP. Now in a GT, hell yea(Ktlplxm)! But to each his own.

If you go through with the swap I'd love to see some pics/vids etc etc. Welcome BTW.:)

Where are you located? Whats the DA at the track?

['02 ws6]

I was wondering the same thing.

I'm curious as to why you bought the Gxp instead of a Gt. Buying an auto and plans of changing the motor has me curious.

Anyways, nice runs.

[c5racr1]

bought the GXP instead of the gt because it has the suspension, diff, bumper covers front and rear that i liked, and the ls3, which will fetch a much better penny than the l92 motor. the ls3 modded will make simular power to a stock LS7. but I have a LS7 in my caddy ctsv(04) and with headers and a basic tune it put down 498 rwhp, and 468 rwtq corrected. that was from a stock crate motor with headers, It has also run 119 mph in the 1/4 mile. I don't think any ls3 m6 is even close to that. Dont get me wrong I like the ls3 but it is no where close to an LS7. coupled with the fact that I have the motor sitting on the ground not doing anything.
ask yourself, if you had a ls7 engine sitting on the engine stand in your garage and it was paid for, and it was going to cost you the less additional money to mod the motor, and about the same for converter and headers what would you do? I know what i am going to do!!
As far as the install goes I will do it myself, with the help of my brother and a close friend, it is not that hard to do, it is apples to apples, not like apples to
oranges like in the ctsv. reason behind getting the auto is that I don't plan on doing any more road racing, which was the reason behind the ctsv, just drag racing, and auto's rule in drag racing. with modern converters it is quite possible to have a daily driver that will cut 1.5x 60 ft times with some et streets.

if you want to impress the girls get a m6, if you want to win the drag race get a a6.

[c5racr1]

as far as the density goes I am in south louisiana which has dense air, unfortunately it comes with 70% humidity, thats the trade off. burn thin air or burn thick air and water. trade offs always. in the summer we have to run i 90 degree heat and 90 percent humidity, try to make good power in that.

The ls3 modded will make simular power to a stock LS7. but I have a LS7 in my caddy ctsv(04) and with headers and a basic tune it put down 498 rwhp, and 468 rwtq corrected. that was from a stock crate motor with headers, It has also run 119 mph in the 1/4 mile. I don't think any ls3 m6 is even close to that. .

I'm sure Chris (GTPprix) will have something to say about that when is Maggie install is done in his GXP.

498/468 is a sick set of #s btw, my point wasn't diminishing the ls7, just saying that the more extreme mods (FI, nitrous, stroker) aren't really compatible with it, due to it already basically being a max effor build by GM.

[c5racr1]

well compare apples to apples, If i put FI on a ls7 then a maggied ls3 is toast. and I have been working with ls7s since they came out, they got a bad rap about the "weak" blocks, that was snake oil put out by a couple of tuners who didnt understand that motor, in the beginning people were putting nos on them and kicking rods out and everybody jumped on the bad block wagon when it was actually titanium rods and nos, don't mix at all, tie does not bend so whrn they would put these huge 250 shots on the z06, and detonate, it would fracture the rod. I know personally 3 z06 s with chargers, nos or stroked motors running full weight in the 9s at over 140 mph, that will not happen with a weak block. Katech builds a air atack LS7 with fi that makes over 1000 hp with a stock block.
when home boy puts a maggie on his Ls3 he will be making around the same power as my NA ls7, not impressive to me. suppose I want to counter his maggie with a APS twin turbo setup, that is 900 hp on a stock LS7, check your facts

[c5racr1]

and by the way as far as being a max build effort not even close head and cammed LS7 put down 650 hp to the wheels all day long, check with any tuner.

What I got was the internals are max, TI rods, crank, etc., no?

[ThugHunter]

c5racr1,

When is this build happening? I'd like to follow it to see the results.

[Darkside]

I get where you are coming from, just think it would have been much cheaper to do to a Gt. If money is no object than a Gxp is much more appealing.

What times did the caddy run with the 119 trap?

[c5racr1]

if you are talking about running a 250 shot I wouldnt do that on any motor without forged pistons, so in that respect i wouldn't do that because it may go:poof:

but as far as staying NA heads cam and intake 1 7/8 headers, depending on how radical you are willing to go on camshaft, which I am not :) 650- 700 hp is quite attainable. now once you start running power adders, the rods and pistons are normally replaced, but not always, APS has a kit for ZO6 that puts down 750 with the stock bottom end, then a very very good tuner comes into play! detonation is the killer.

for what I want to do, run 11s on the motor all day long, a mild cam, and bolt ons will do it.

the caddy ran between 12.5s and 12.8s at 119, but the caddy's rear is junk which limited my driving to 2.5 60ft times and granny shifting! the one time i tried to get halfway aggressive. the rear end shattered, before i got to the 60ft! so whenever I took it to the drag track I went to run MPH only, which is the main reason for getting the GXP!

I plan on starting theswap in 2 weeks, definately whin a month depending on the weather, should be a 2 day job. .... famous last words.

I plan on using the stock tune from a 09 Z06 as my base line, wiith a cut and paste using HP Tuners, worked last time. And FYI my2009 GT, GXP now use the 87 mm ZR1 throttle body which is NOT the same as the 90 mm from 08 on back So.... all you 09 guys dont get a ported 90 mm because it will drive the computer crazy.:puke: V max motorsports found this out.

[NAiLs]

Very interesting read. I can't wait to see how this swap comes along! :) Hopefully that "2 day" plan holds! lol

i messed this one up, at the line. long story :)

all runs were somewhat hot on the IAT cause the staging lanes were long and the MAF would heat soak.

all and all i am happy

next mods are

my guess is 11.30s at around 118-120mph, we will see!:woohoo:

Nice runs! What are your plans with the LS3?
