What is the best e.t.'s/traps, one can expect from a v.550(stock, unbuttoned longblock, no drugs, stock intake manf.,TB&MAF) equipped with a 3071R on race gas? Can one get into the eleven teens, with that turbo?

Also does anybody have installed pictures of stage 2/3 installed?

11.1x is pushin it......11.4-11.8 is more doable with traps around 120-124.

if you keep the stock heatshield in place you cant even see the turbo upgrade.

I didn't think anyone else currently posting on EvoM had a Vishnu 3071 but me. The red shop car had one (and that car was stronger than mine). There are a few more 3076 cars, though, and they are definitely a little quicker in the quarter than the 3071 will be.

My run was early summer in mid eighties heat. It was a week before my custom tune, and basically it was my pump map at ~25psi with a little extra timing. I'd guess it was around 360-370whp. I feel that with Shiv's race gas map it'd drop about 3 tenths and gain around 3mph.

I am running the Vishnu 3071 but have not been completely tuned as yet. I'm also running a cat so that's going to affect things a bit.

sparky remember that luis gerardo cuellar with his 91oct map for the v550kit(3071) he beat up really bad a stock porche 911 turbo(2002model) easy 6 car lengths and with race gas it would of been worst for the 911!

Yeah, the E.T.'s are just about what I figured guys, thank you all! I figured it for mid-elevens w/o drugs, depending on track, driver and ambient conditions. The 3071 is really quite impressive on racegas. I am guessing that these nice times are on high performance street tires.

With Alky added into the mix and a good launch , then they should be capable of 11.20's-11.30's, huh? Kudos all, and keep up the great driving Conversely, on pump gas w/o alky we are talking low 12's like 12.20's-12.30.'s. Thanx. Wow, even on pump gas, it's like driving a Viper.... powerwise, on the street.
