50 trim srt4
buddy of mine has a 05 white srt4 with a very extensive mod list with all the bells and whistles, 50 trim turbo, return fuel system, ripp mods dyno tune, coilovers, everything, car made 410hp and 402tq, so we went for a cruise the other day, i wanted to do a 60 roll to see if he'd walk me, so eventually i get him to race, 3rd gear 60 roll up to about 115 - 120 ( he let off before me ) we were dead even till we let off..
is something not right here?
i dynoed 375tq and 339hp .. mods or trifecta 24psi tune, CIA performance charge pipes and CAI with tial bov, and MAF relocate kit, pedders spring, and full exhaust with only a cat on it, its loud ..
he didnt say a word after

My cars the one with the 26 lbs turbo swap. When those vids were taken the tune on the car was conservative, with a fucked clutch, and bov leaking.. since I got the car I've fixed almost all the issues. I'm waiting on my direct injection pump to start tuning. Ill tune it for 26lbs and I'm hoping to get 18-19 degrees of timing without meth.... so I will see. Btw my cars badbaltguys old one with the hahn setup....
My mods? GM Stg2.

yea its definitely the lag
did he start to pull on you before he shifted or was it dead even the whole way through? if it was dead even the whole way something is terribly wrong. also what kind of dyno did u measure with?

[QUOTE=08ShowbaltLS;5411083]dont know what to tell you. his car must have been acting up or his dyno was off[/QUOTE
his catch can was FULL we realized after we did the pull he started smoking bad lol, think it could of caused a pressure build up of some sort?

Driver mod FTW... I pulled a 35r SRT-4 local to me, and my **** was stock with a tune on E50. I brakeboosted and powershifted, and he didn't know what either of those things were.
Sad part is this is my first turbo car and I had it for 2 months at the time and he'd had his car for years.
What it comes down to is that on the street, anything can happen... And turbo vs turbo on the street, when it's close, the turbo that spools first wins unless you race to ridiculous speeds.

Left foot pushes brake... right foot pushes gas... spool that bitch up before racing and you'll be fine.

That may be true but there is a difference between absolute peak power and usable power.
What about shifts? Are you going to NLS pushing almost 30psi on a huge ass turbo like that? Or are you just hoping that a shift isn't required?

Wrong...60-100+ tells the *story* as far as HP goes. A win on this roll goes to car with better HP/WT..unless something is wrong. As I posted earlier, there is some leeway with this...being torque curves. Third gear would have to be really bad (as you indicate) and that *could* effect the torque curve, but I doubt it's THAT bad. For the most part it's HP (to wt) that determines who win's this type race.

Yeah... a bad driver can still cause a car to lose a Roll Race. Granny shifting gets you no where fast.
Haha... you're crazy. As long as you aren't taking 2 seconds to shift gears... you'll be fine. I have a "big" turbo on my car and if you shift fast... you won't lose a lot of shaft speed on your turbo, therefore you will get back to full boost very quickly. WOT shifting is much faster... but you can still be plenty fast without it... you still need to shift quickly though.
Some of you people have a lot of MYTHS stuck in your head about "Big" Turbos.

You may keep shaft speed but you are losing your air charge if you are running a BOV. So you would have to recompress the air. I agree that it would take less time than initial boost becuase you already have higher RPMs and more airflow but you will still lag. I just think that there are better routes to take as far as add ons go. Just slapping on a huge turbo isn't always the best for a little 2.0 liter. I guess it depends on what you want in the performance aspect of your ride.
Well yeah... you really only need a GT2871R to make 400whp on an LSJ/LNF... thing will spool instantly too. There is no need for a GT35R or a giant Holset like he has... 
Either way... a lot goes into lag, etc. Ultimately, his set-up will dictate a lot of that. If you've got 3" charge piping all around... that'll spool a good bit slower than 2.5" all around, like I have. Same goes for a huge intercooler with a lot of volume to fill.
