Can'tHave2MuchHP

Hey guys, I want to do a build car, mostly myself, except for tuning and possibly some really in depth work, and have a good deal on a 2011 Grand Sport with 6700 miles.

I'd like to be in the 700-800 RWHP range with the option to go bigger in the future. I don't have a problem with making over 800 wheel, no big deal. So I'm thinking a D1X or D1SC (Or other model) Procharger or an ECS kit with 1500/2200, with a blower cam and maybe heads. What do you guys think I'm looking at power wise out of that? Stock bottom end LS3, obviously, and how do you think it'll handle the power? How much am I looking at building the bottom end if the stock bottom end can't handle it? Besides the bottom end, where will my other weak points be that I could look into reenforcing when the engine is apart?

And for a cam, I'm not sure on any details. Not an expert on cams, but I want something that's going to chop but also be drivable on the weekends, don't want a Stage 5 cam that nearly stalls in-between (As great as they may sound ). So yeah, a nice in-between cam is what I'm thinking.

If I can get enough of this info, I'll get the deal done and make this a public build Thanks guys

D1SC would work best for your goals. Detoxx, here on the forums, made high 800s on a stock bottom end LS3 with D1SC. I would hit him up for his build details.

Why would you want to use the D1SC over the D-1X which is just the newer version to my understanding? Makes 10-15% more HP on the same amount of boost, I believe they claim, while also running cooler temperatures due to a redesigned impeller system or something.

For your power goals, the D1SC will make more torque down low. D1X will only outperform the D1 in the upper rpm range or if spun hard to power levels beyond your goals.

Can'tHave2MuchHP

Thanks I appreciate the info. Will look into it.

I'm still on the stock bottom end LS3 with stock heads. D1SC made 840 on pump and 881 on e85. D1X makes 933 and a little less torque but I'm moving from a Mantic twin to triple so we can complete the testing. Don't need to do a lot to achieve your goals just good fuel and a proper tune. I would stick with the D1 for your goal range.

Can'tHave2MuchHP

Thanks a bunch man. Just did some research on your build and I really like it. Do you run Meth? I really want to just run on 93 with no meth for simplicity.

I'd also not do heads to save time and money if those kind of numbers are possible. What did you do for fueling to run on 93 with the D1SC?

Detoxx03

93/meth and I left it on for e85. Doesn't hurt anything and doesn't make it any more complicated. Wouldn't even try to run just 93 at those levels. I did at 630rwhp but after that I added meth. E85 is everywhere around here so no reason not run a flex setup.

Can'tHave2MuchHP

Yeah I figured as much. I'm north of Detroit, around the 23 mile area, and yeah we have it all over. What's your meth setup?

Detoxx03

Yeah that's north of me. I run a alky control dual nozzle setup. If I had the car here I would let you check it out but I have to go to Louisiana next month to pick it up.

Just 93 won't have enough octane to make 800. You need meth, race gas, or e85.

Any basic blower setup (D1sc, A&A or ECS) will make 800 with ease. Stock bottom end with good octane/tune is fine there. Spend the money on drivetrain, cooling, fuel system. Stock heads should be fine there too.

Get a proven blower cam, or have someone spec you one for your goals. BTR has some excellent cams that are proven, or go with a Pat G/etc for your combo.

Awesome info, thanks a lot.

I'm just over 700 wheel with a little V3 Si on a stock LS3 and Z06 exhaust manifolds with 93 & dual nozzle 100% meth. I doubt I could hit 800 wheel with my little baby blower, but even I could probably be mid 700s if I did cam & long tubes.

Can'tHave2MuchHP

So if I do injectors and flex fuel sensor, will I be able to fill the car from empty on 100% E85 without worrying about mixing/moving pumps and BS like that?

Also, can anyone give me a rough number on a Alky Meth kit + install/setup?

EvanZR1

No, stock fuel system won't handle E85, you'll need to upgrade. That's why so many of us run meth, you can run stock (or stock with BAP (boost a pump)) with meth and make 700-800 no problem.

I paid right at $1,000 installed for my Alkycontrol dual nozzle. This was using the factory windshield washer tank, which will give you a warning when it gets low.

Can'tHave2MuchHP

Yeah, at this point I might as well do both E85 and Meth, at least that's what I'm thinking. I now just gotta look into fuel systems. Any suggestions? lol

Detoxx03

$1000 seems like a like for the alky kit. I paid less through ECS. I run a Fore Innovations triple pump kit setup for e85.

Can'tHave2MuchHP

Thanks for the info so far guys, writing all of this stuff down for sure.

Stock LS3:
D1SC Procharger kit
Cam (Still have to figure out details here)
Headers (2" ARH or Kooks)
Flex fuel sensor (DSX?)
ID1300s and a fuel pump setup
Alky methanol kit

What else am I missing?

EvanZR1

I wish I had just done the fuel system when I originally did the blower. Of course, I also wish I did the T-trim instead of Si-trim. ECS, A&A and/or Fore all make good fuel systems. Personally I'd probably just do a Fore Triple and do it once.

$1,000 was including install and also part of that was work fabbing up new charge pipe for speed density.

Here's a question for ya, go here and look at their "kits": http://www.foreinnovations.com/category_s/492.htm

For my build, would L1 be getting to the top and I should go L2 just in case or will I be far enough below 900 to not worry?
