Okay i have done so many searches and not really got the information i want so i wanna post up and ask you guys what turbo you are running and what rpm's you reach full boost. I am really wanting to buy the atp 3037s kit but im not sure about the spool. I am also condsidering the ams kit but its not much different from the atp kit and like 2 g's more. I would perfer if you had these rpm's data logged. Not what you thought you saw your boost gauge hit at whatever rpm. Thanx!!

 

ATP 3037 would be a very poor choice. Why would that even cross your mind? There are many turbos that are far preferable, and none of them are made by ATP. Spoolup will be different for every car on the same turbo and significantly different for different turbos. There's a reason why AMS's turbo kits cost more - they actually make power.

 

2300rpm on my modified DSM 13g. I figured forget about peak power, I want instantaneous response!

 

There are a TON of variables that will affect when you reach full boost. I agree with Warrtalon, the ATP is definitely not the best choice as it is probably the worst spooling kit out there.

If you haven't modified your car yet at all, then you might want to start small (e.g. tuning, cams, exhaust).

Some things to keep in mind regarding spoolup... These are general rules of thumb (some of them, I'm sure you know), there are exceptions to these but not many:
- bigger cams = later spoolup
- cam timing = later or earlier spoolup, depends on the setting
- bigger IC = later spoolup
- SS exhaust manifold = later spoolup
- smaller turbo = earlier spoolup
- bigger turbo = later spoolup
- poor choice of turbo housings = later spoolup
- aftermarket intake manifold = later spoolup
- ported head = no change in spoolup, but softer ramp-up of spool
- larger displacement = earlier spoolup

Yeah i know of most mods that will either help or decrease spool. Mainly, which i forgot to mention, im lookin for spool times from 2.0L's. I have all the supporting mods. I have 02 housing, invidia downpipe, test pipe, tanabe exhaust, megan racing manifold, aem intake, turbosmart bov, walboro 255, sun hyper cyber speed voltage and grounding kit, with gsc cams on the way. I also will be upgrading the intercooler as soon as i figure out what turbo kit im going with. And i have ECUTEC with the stock ecu and i also have a utec which im about to install so i can get a race gas tune. I want to make good power but i dont wanna wait till 5500 rpm to get it. Im just lookin for a good gt30r kit that doesnt take forever to spool.

 

get a gt35r forget about the gt30r because that was my last setup,
the lag between them 2 r about the same and the gt35r makes more power

 

I have seen the gt35r on a 2.0 not reach full boost until like 5300 rpm. Your right it does make way more power but the gt30r is a more streetable turbo for autocross. The gt35r isnt good for that. I drag and autocross and the gt30r is the choice for me. I dont wanna go with a stroker kit, im just looking to put down almost or right at 400whp on pump and 450 or so on race. And i know the 30r will get me there no problem.

 

The GT30s are not good for autocross at all, especially not an ATP 3037 (or any ATP kit). The best of both worlds is a BB 50-trim from AMS or TT.

 

My buddy autocross's all the time with his gt30r. Yes they are good for autocross.

But lets try to stay on topic here. This thread is about spool time not which turbo is better. Im lookin for some really usefull info so im not dissapointed with the kit that i get. Thats why im asking you guys who already have some of these kits and know how well they perform.

 

Just checked one of my logs on the AEM on a dynojet dyno for ya...

10.06psi @ 4211rpm
15.17psi @ 4500rpm
20.46psi @ 4715rpm
25.35psi @ 4871rpm
30.15psi @ 5055rpm
35.26psi @ 5324rpm

3rd gear pull... spools slightly faster on the streets. Mods are in my sig.

btw, the turbo is a gt3582r

 

gt3076r with a .82 backend... 4800 rpm 29psi.

 

Nice, what kit???

 

Thanks for checkin that for me, and damn your pushin alot of boost!!!!

 

I autocross all the time with stock suspension - that doesn't mean it's good. Your buddy may autocross all the time with his GT30R, but that also doesn't mean it's good. The GT30 is _not_ a good autox turbo - plain and simple. If that isn't important, then fine, but you stated it was an important factor. I don't care which turbo is better either - I'm just telling you it does not spool quickly, especially not for autocross purposes.

 

You mean 13b...and we are talking about Evos...you obviously don't have a 13b on an Evo...
