Is a wastegat dumptube necessary, i dont recall usually seeing these...where does the dumptube run to?

 

yes it is, keeps the engine bay clean and makes more power than no dumptube..... as for where it goes, just run it down so it stops below the oil pan.... thats it

 

where would i be able to pick one up at? and while on the topic..im looking for about 400whp on my lsvtec yes built internals if you need details just let me know...but would a 38mm wastegate have too much stress on it? or should i just play it safe and go w/ a 44mm
*edit* just saw fab-works in your sig*

All depends on what manifold you have.

Ben at Importparts.com has dumptubes for like $30-$40 bucks if i remember correctly. Also full-race and Lovefab have them as well..

 

I had mine coming out of the side of the front bumper when I had a body kit. It broke off once right before a local dyno day, and I wanst thinking about it and when I dynoed I made 223hp, and it was so rich it was off the chart. 2 months earlier when I got it tuned I made 317hp and the A/F was perfect. Ill find a pic so you can see that without the dumptube its blowing exhaust right near the inlet, Im lucky I didnt blow my engine after seeing the A/F ratio...As of now its directed into the fender well, shooting right at the tire.

 

Bluffton, huh, I guess you know Derick over at TruBoost? I used to live in Laurel bay back in the day. What do you drive? I have a 00 EBSI but I have not been there since being on leave in OCT 04. Got any pics of your ride?

 

im prob. going to run a shorty mani unless if i can my buddies ram style..and as for the wastefate size, will 38mm be pushing it too far? thanks guys

 

i would get a 44mm (what i use). im gonna look into something bigger for my app since i should be getting a gt42r soon

 

niice, yeah im buying my buddies garret t3/to4e 57 trim inc. downpipe for $500 i got a pretty damn good deal lol, and the turbo only has 300 miles

 

I have no information to add to this thread.

Just wanted to say this is an amazing post. Great information. Keep it up.

you know a bigger wastegate only allows you to run lower boost...
Look at alot of the big turbo supra's running small wastegates. It allows for higher boost.

Ryan Woon - 1400whp all Boost 44mm Tial

 

well if im looking to run no more than 16 psi but usually around 14 would you reommend a 44mm? id like to maybe even drop it to 10 for usual DD

the smaller the w/g doesn't allow any higher boost than a large gate. boost is determined by the w/g spring pressure. the reason ppl run larger gates is better control of lower boost #'s with larger turbos so you don't get creep. manifold design plays just about as much of a role in this as wastegate size

 

so then for me running a t3/t4 id prob. want a 44mm to minimize boost creep?

 

it depends on what manifold you're using and how low of boost you want to go

if you run one of hte ram horn manifolds...you'll need a larger gate due to poor wastegate placement.

and if you run a t3/t04R or soemthing...and want to go down to liek 6psi...you'll need a larger gate.

for anything smaller than a 60trim on just about ANY manifold....a 38mm gate is usually good enogh, though

 

sorry not to give specifics Garett T3/T04E 57 trim most likely on a shorty style mani

um, no.... i can run the same amount of boost on a 60mm wg as i can on a 3mm wg, the bigger wastegate just flows more, which is better at controlling spiking and creep. i have a 44mm wg currently but am looking into a 60mm hks style wg

 

You really only need a bigger wastegate when you know your wastegate is fully open and the boost starts creeping.

 

right now im not worried about creep... 2liter ls.vtec.... fully built, ported polished head, radical cams... custom built gt series turbo, top mount or peakboost manifold, central wg location... a little direct port shot everynow and then

in the near future im getting a gt42r and bumping the direct port shot to 125.. thats when i start worrying about the 44mm begging for mercy

 

so a 44mm wastegate would be good for a gt35r

 

with a full lenght manifold
