I really liked the video thanks for posting it. Quick question though. You said you got it to go 9.9 at 144-145, was this on the same combo with just more seat time or did you change it up for more power?
Thanks man, when it did 9.9 it was at 745 rwhp. 3.4 pulley still. To get from 710-745 I changed the meth nozzles to dual 10gph and also did an iat breakout. I believed the car was pulling timing even with meth. The iat was read prior to meth nozzles so it could potentially pull timing thinking iat was more than it was. So added the iat breakout, dual 10gph 100% meth (vs dual 5gph 75/25 meth to water ratio), and 2* of timing. I think it was 19 degrees max. Added a drag pack. Skinny front and 26” Hoosier rear.
@@deadly4orce That's awesome man! I was just curious because 144-145 on an Si head unit is moving! I have a 1500 SL (Ti) head unit maxed out and about 18* of timing on E85 but I'm high elevation (5,800 ft) so I'm hoping to hit about 135 ish this spring
@@scottgt95 thanks again, yeah that car ran its ass off. Full weight besides drag pack and pulled front sway bar. Nothing special. Stock suspension and driveline besides mantic clutch. Your elevation is definitely a challenge. You should do well regardless though!
@@scottgt95 honestly probably not but I was going to have to do everything I could to get the best 60’ and it’s recommended by many. It took me a 1.50 60’ to get it done. Most runs on a regular tnt night I sixty 1.6x - 1.7x and would run 10.2-10.4. It was all in that 60’. They had a slicks only night and actually prepped it well and I chalk up that 9 to the prep. It just hooked.
What are the specs on your cam? I have a similar ls3 setup with a v2si on 3.6, A&A stage 1 Fuel, Meth, my cam is 220/230 and I'm wondering if a 3.4" can get me into the 700's. Currently at 620/570 right now, tune is conservatively rich by Andy from A&A.
jpshoar 226/238. If you spin the 3.4 and have all the same pieces as mine. I don’t see any reason you won’t make 700. I’m on 18* of timing and 11.3-6 afr on the street
SpeedLife301 heatsoak was never an issue with so much meth but I did want to go v2 T trim (better bearings and can be overspun vs v3 self contained) 8rib direct drive, 10% overdrive crank and make 800-825. Ended up selling it though
mindovrmatter33 slow. 154 I think. Had some fuel issues when I first got it and was pulling timing. Also it ran out of 4th before the line. I made changes to the meth, pulley, fuel system, and tune after that but never did the half again as 4th was too short. Ended up running 9.9 best and 144-145 several times in the 1/4 before I sold it. If it had the right gearing I’d say 170-175 was doable in the half mile all dialed in.
Alan Ross yes, stock head bolts, heads, intake, Tb, and driveline. Basically everything was still stock besides blower, cam package, headers/exhaust, meth system, auxiliary fuel system, and clutch.
It ended up doing 9.9 best et and 144-145 in the 1/4 after mild tweaks. The video was prior to correcting issues and swapping to a 26” Hoosier from a 28” m&h. That was a terrible tire for a manual.
@@deadly4orce your mph says the car should be low 9's if it did 145mph. 135mph is a high 9 second car. ET is slow for the power. Stick is killing the ET. My car makes 540rwhp and has been 10.72 @128 weighing 3660lbs.
@@wallyc7349 Et is more to do with the 60’, DA, prep, gearing, etc. it’s not a drag car it’s stock suspension 37-3800# on a 17” nitto drag radials. Yes I’m aware similar weight less hp cars go faster with less mph. I sold it 3 years ago so it’s moot point now.
Damn, one bad ass Grand Sport! Coming from a C6 Z06 owner
Thanks man, actually sold my c6Z to get the GS. Both great in their own ways!
Perfect build my dream to do all this to my vette
Man that thing eats!!
That car should have had a Ti head unit at the very least, would have made more power, outside of the efficiency range of the Si.
Nice, but the moment you throw a rock through that unprotected fuel pump assembly, youll be sorry!!
Turn off the damn music!
mattdracing18 glad it’s my car and video lol. That’s what I like
BADASS
I'm wondering how you're getting a flutter sound off of that ? Did you modify your bov ?
It was the BOV that was with the base kit. 38mm turbosmart. I swapped to a 50mm raceport turbosmart and that was a solid woosh noise and much louder

@@deadly4orce I'm hoping so. I've got a drag pack but full weight and stock suspension otherwise. Did pulling the sway bar help a lot?

You made 660 on the boost a pump? What kind of fuel!
Yeah, had to swap to the secondary pump to go past 700 safely. 93 / meth at 670 it had dual 5gph nozzles with 75/25 meth water mix
What injectors were you using before and after the ECS stage 1 upgrade?
It was the same 80# injectors. Being pump 93 it was enough. Plus meth supplied a nice chunk of the octane at WOT.

I'm seeing low 10's on my AFR.
Upgrade to the Ti you can make more power and spin it slower. Less heat soak
SpeedLife301 heatsoak was never an issue with so much meth but I did want to go v2 T trim (better bearings and can be overspun vs v3 self contained) 8rib direct drive, 10% overdrive crank and make 800-825. Ended up selling it though
Need some welded wheels would really set that thing off
what use gas? 93 pump gas or vp fuel?
wl rks 93 pump gas and 100% meth with dual 10gph nozzles
When you ordered your kit, did you get the dry sump radiator add on? Or did you just relocate the oil cooler?
Thanks
albert lassacher dewitts radiator with the kit
Was this the regular ECS fuel system or the E85 fuel system?
Kam Fam regular ECS stage 1
What shifter and knob is that?
MGW on both counts
@@deadly4orce thanks
Where did you find the rear wheels? Can’t find that offset anywhere
EVL LS3 I got lucky on a forum and a guy had them brand new for sale
Good God how I want the A&A setup on my GS, your car is tits
Vette dude played music???? I thought only rivers did that???
Nice
Nice! What was your half mile mph?

Around have been better if you took off the music
So was that set up on a stock bottom end?
yes
Alan Ross yes, stock head bolts, heads, intake, Tb, and driveline. Basically everything was still stock besides blower, cam package, headers/exhaust, meth system, auxiliary fuel system, and clutch.
Great car and build, but super slow 1/4 mile for 710rwhp.

How much boost does the 3.4 pulley give you? I'm either going to pulley down or go to a YSI.
r3drumz _427 it gives me 9-10# at 6,500rpm
Hey man, where did you run the dyno at?
Looks like the car is up for sale and I was wondering if you could give some insight on the car.
Max Olcat sure. Email me your phone number and we can text all that if you’d like
@@deadly4orce thanks man, I emailed you.
