They are extremely good so watch your sarcasm buddy! A 2.5" 02 housing with 2" dump on a Red is worth 15-20hp vs. the 3" 02 Housing with a 2" dump worth 20-25hp plus will help spool. There is a reason why every aftermarket turbo comes with a dump/dump option. They make the most power. On a 35r dumps are worth 40hp at the 600+ level.

^^^what is a good 02 dump for Red/Black or bbk?

 

easy there Mikey, I know how ya like to push your sweet O2 dump! Very setup dependant and aftermarket turbos are a whole different ballgame compared to the stock framed ones.

They might have their place but I'm tired of seeing all the O2 dump blanket statements about how they are the be all end all solution for all turbo problems...

 

Okay how about you inform me, since you think you are right... Sure dumps are "setup" specific but the stock framed turbos are making almost the same power as the gt turbos, but trust me they work wonders! Clearly you don't have one and are just upset that other people are making more power than you.

There are no "blanket statements" about the dumps. What do you think the limiting factor is on the stock frame turbos? Lets see if you can figure that out and why the dumps will help stock frame turbos more that a gt frame turbo?

I've run the car with the dump and without. It's clearly shown in multiple threads that setups affect the hp gain of dumps. Some gain power, some lose power, some gain nothing. I hated the sound of the dump...though it made the car sound terrible and I didn't see any gains with the small cams and 91 octane

You must not read a lot of threads on these...almost everytime stock turbos are brought up someone says "put a dump on it...they're sweet! you'll make like 50hp and spool 1000rpm sooner"

Believe me I'm all for performance and I'm not worried about other peoples "numbers" you just seem to have a problem when people don't agree with you and are WAY overreacting on this...

 

Dude I'm not at the slitest upset or upset if someone doesn't agree with me. I just am very hard set on the dumps making great power. Also you have to look at the design of the dump before you classify all the dumps in the same category. I agree that some dumps won't make power nor help you in any way. However, a well designed dump like the JMF or Shearer 3" will show gains on any stock frame turbo. My friend just make 420hp 28psi unported stock manifold and unported stock turbo, stock cams, stock IM and TB, just basic bolt ons. I have not seen hardly any cars make that power. I had to run 1500cc of meth, and cams to make that power on a recirc. I had almost every mod you could without going to extreme. There is a reason he made the same power as I did on a lot less mods and on 3psi less boost. Call it what it is.

I don't rant or ***** about dumps on hardly any thread any more. Most people ask me questions in the threads or send me a pm. I will help people if they ask. It is 100% okay for use to disagree and think two different things. But it is also 100% okay for me to voice my opinion when I see dumps making power all day long.

If you want to chat more about the dumps we can in pm. fyi, if you tear drop the dump it changes the tone a lot and it sounds amazing. not a raspy exhaust leak.

Mikey

 

what do you mean by tear dropping the dump?

 

Ok I've had my fun with this now I was never debating that dumps made power since we were talking about spool before we went off topic. Sparky made a good point, I agreed, would like to have seen the guy that said "get a dump" chime in and explain his case and we had a little fun with the topic.

No hard feelings here Mikey, like that build by the way

 

The only dump that will increase spool is a 3" housing that removes the donut gasket between the housing and dp.

Thanks, I have spent a lot of time and money on it. I'm loving it so far!

i have a few ideas that dont seemto have been mentioed:

Anti-lag (BANG-BANG type)
N2O - just to assist sppol 25bhp to a 50bhp shot should be more than enough.
More compresion - If you are building you motor try runnign a little more comp. just make sure you tuner is aware of this as they might have to yune a little more convervatively.
Exhaust manifold - its a creitical part of the system. maybe look at getting it coated and then wrapped with header wrap. should keep a little more heat in.
Turbo blanket - as above retain more heat.
Better cams / timing - timing is the most important!!!!
Sequential shiftter - anything that can reduce the time of shifting will reduce the lag of the turbo between shifts.
Free flowing exhaust - getting the exhaust out of the turbo is JUST as important as getting air to the turbo.
BB option - these are avalaible in the UK i think. Should help somewhat with spool.
TUNE - a more aggresive tune, esp in the no boost area, should reduce spool up times

the list gose on and on and on. .....

i would go with the fp green hta 73.....that **** pull ***ing hard bro.....mad hard

 

i think a red is the way to go ... not to big defenitly not small!!
perfect for the street and track but maybe to big gor auto X ?

Goog luck

 

trade you my red for your black which spools alot quicker!!

 

just remember the longer the runners on the turbo manifold the more lag you will have but the greater top end power you will have as well, thats the reason the cars making the big big power are either front facing or top mount manifolds with long runners. But for a street car shorter runners will give ya faster spool, that and correctly made manifolds that flow the smoothest
