For a true comparison, you need the same driver to do 1/4 runs in the exact same conditions. There aren't many, but those who have have knocked off about 1 second.
What do you mean there arent many. Do you mean not many people have knocked a second off? Because if so, you are proving my point. Or do you mean there aren't many greddy owners, because im sure there are hundreds.

Lets think about that for a hot second...after all this do you think I'd be helping to prove your point? There aren't many that have done a 1/4 mile run before and after turbo. There aren't many that have done n/a 1/4 mile runs, and there are even less that have done turboed 1/4 mile times.

Moostafa, im not trying to have a personal argument with you. If you have facts that you can post, i'd be glad to see them, because i haven't seen any that clearly point to mid 13's. If you have factual information (not people saying the car is much faster) but rather drag numbers that you have actually seen, please post them because i would honsetly be ineterested to see them.

I don't want to argue with you any further either. I have not seen a mid 13 second run, as I've only seen one true 1/4 mile thus far. My only point was that if a person with a boost leak pushing 220whp could manage a 13.9, it is possible for them to get mid 13s if their car was properly functioning. That being said, here is your gtech comparison, done my a race car driver. Given his rep, I trust his results.

There was a poster here that went from 15.1 to a 13.9 with his kit (wasn't Polak, off the top of my head I seem to remember it was one of our Canadian members, maybe Luis Schiavo). Honestly, I have not seen very many people pulling 14.5's with a stock car. Did the magazine do it...yes, but that was that driver in those conditions. Most times I have seen are in the high 14's, low 15's. To get from low 15's to high 13's is 1+ sec. drop you were looking for. Haven't seen any 14.5's to 13.5's simply because I haven't seen many 14.5's outside of the magazine.

I'll post my 1/4 mile times as soon as we find one close to us. We have 3 1/8 miles pretty close but no 1/4 miles that I know of. My fastest 1/8 was 8.7 sec.

a more realistic comparison is a low 15's high 14's to a mid 13, because 220 whp is not the average here, its more like 240 plus.

Greddy turbo isn't fast at all. you'll have chance on N/A cars with simple bolt ons, but not factory turboed cars such as evo, sti, srt4.
srt4 with stage 1 ecu will be just as fast as greddy turbo with interceptor-x.
and stage 2 ecu will murder greddy 8.
if you want to hang with those cars that are slightly modded, you don't want greddy.

If that interceptor x really does the job then the next thing to find out is how much power our 8 can handle along with the tranny and all that usual stuff. Then If you have a greddy kit already, then just get a bigger turbo.

I'm not so sure its as easy as getting a larger turbo, as there is hardly any space to work with as is. I could be wrong though

You're basing this on pure conjecture. An an incorrect one at that. From a roll I have run with EVO's & STI's and stayed dead even/stayed ahead of them. You should see the looks on their faces, it looks like I just ran over over their dogs. Then they hear the BOV & understand why. STI's & EVO's make very good 1/4 mile times because they have the AWD off the line, but have you ever seen their 30-50 or 50-70 or even their 5-60 mph times (rolling start). There are good, but substantially off their 0-60 or 1/4 mile times.

you have to read the post more carefully before saying i was making wrong statements.
i said slightlt modded, which means ecu, boost controller, exhaust.
those are pretty simple mods. you ran stock ones not slightly modded ones.
you run those i mentioned, and you'll get murdered.
greddy has its limit and that's that, no questions or 'bashing on pure conjecture'.
srt4's stage 3 ecu gives u somewhere around 350whp, and its not even a major upgrade like bigger turbo upgrade.
you're proud because you can keep up with stock evo,sti's with greddy turbo?
i wouldn't consider greddy fast AT ALL.

It is worldwide known that evo's top end is horrible. But with the cam upgrade, that could be alleviated. Does greddy offer high top end? I don't think so.

I have two friends with WRX's. From a stand still they are much faster but from a roll things are different. Fron 10 mph I can beat an 05 every time. The 06 is a drivers race. AWD has a hudge impact of 1/4 mile and 0 - 60 numbers.

Fast is relative. Any car the can do 0 - 60 in the sub 5 second range is fast to me and most people.

No, I've read your statement. The beginning part of it states that I won't have a chance with factory turboed cars, such as EVO, STI, & SRT4. I am saying that I have raced 2 out of the 3 & was spot on (Never raced a stock SRT-4 yet). My statement was not talking about your later comment about these cars being modded, it was your initial statement that with a Greddy turbo you can run NA cars with some mods, but not factory turboed cars. That is not true. Can we run with these cars, once they have been modded...no. I've never stated that.

It's not meant to. Everybody reading these threads knows the turbo is small. As Richard Paul put it best, it is a good street kit. It offers good boost on the low end & mid range. The RX8 vs. EVO/STI/Mustang threads have been done before. Of course an RX8 won't be as fast for as cheap as these cars. Hell, a stock NA RX8 isn't as fast as some of these comparably priced cars. This has been said time & again if you want a monster motor this isn't the car for you. The Greddy Turbo kit just accentuates the positive things about this car at a decent price. You can get the 400 whp monsters with other upcoming kits, but be prepared to pay for it. This isn't the car if you want a 400+ whp monster. If you want that then the EVO, STI & Mustang are better for you.

Phew, someone who agrees with me. I'm not saying the turbo isnt fast, but its not even close to the evo/sti/srt with very little bolt ons.

Doesnt the power start to drop off after 7000rpm? I dont think thats accentuating a car that has a 9000 redline, with peak hp at 8500.

EDIT: please correct me if i'm wrong about the power starting to drop with the greddy somewhere at 7000rpm.

But like Fanman was saying, the reason why the evo/sti are such beasts are because of their awd advantage. From a roll they lose that, and are much easier to take on. The srt isn't as fast as those cars from a dead stop, but from a roll its normally even. That being said I think a turboed 8 will surpise most of these cars. But I will agree to the fact that spend 1-2k on either of these 3 cars, they will be out of the range for MOST GReddy turboed 8s.

Agreed.

EDIT: i really would like to know what the power drop off is at with the greddy. I believe i saw something that said it was at 7000rpm. If so, i think that completely goes against the awesome high revs of the car. Once again, correct me if im wrong. This would also be a big reason for me not to get the turbo. I'd want one that wouldnt drop until at least 8000.
