i got some good gains out of it al should be posting up about it soon.

 

im gettin that thing asap. should've takin vids from the front. please please please please please please please please please more vids of it !!!

 

So how where the gains?

SQ

 

Also how much did the unit cost you?

 

I think we are onto something here. I really liked the effect the external dump tube (Hereinafter "EDT") has on tuning. The reduction in back
pressure and streamlining of the exhuast flow seem to really help with the evacuation of the exhaust gases and seem to have a significant effect on how agressively you can tune the car and how far you can raise the boost on pump gas before you see knock counts.

Of course, these conclusions are still tentative and I will wait to draw firm conclusions until I have duplicated these results on a few more cars.

Thus far we did this on two cars and they both picked up decent gains.

The cars make numbers on the dyno AND they feel very good on the road also. Its a very pleasant sound that the EDT makes and I enjoy it.

Cost wise - anyone with a ebay style, Buschur or Megan 02 housing on the car you are looking at 4 hours of shop time $90 per hour and some stainless materials to fabircate the dump tube and the internal block off and funeling pieces.

Here is the dyno sheet

Note * I never finished the tune on the dyno as the EDT melted our dyno straps and we need to order some sheilds for the straps from Buschur before we proceed. I feel it would have made 10 more whp on the post EDT tune if I had had a few more pulls, instead I finished the tune on the road where the knock count was zero and the car ran hard to red line.

 

Al,

Thanks, the car feels great.

I just wanted to add that the temp was most likely around 85-90 and humidity was ridiculous so the weather conditions were not optimal at all.

The dyno graph is a little misleading if you're looking at final numbers because I'm sure after the road tune if we put it back on the dyno, the numbers would be 10whp or more higher...the dyno runs were on 21psi (i believe, al correct me here if I'm wrong) and during the road tune, al turned up the boost so I'm spiking at 24psi with no knock.

The low end feels a lot punchier and the car is even more fun to drive now. The guys at ICS are VERY cool and the owner was always asking me how I was doing and if i needed anything.

I think the second vid shows off the sound well but man it is LOUD when you're in the car!

great job al!

 

sorry bud, those are the only ones i got...too bad i put my camera down when my car leapt off the dyno!

 

The temp conditions were unbearable but the A - B comparision is valid as the conditions were the same

I really feel that this modification is a solid 10 - 15 whp gain

Also - as i said above, it really improves the "feel" of the power band and I think its a harmless easy mod to do - (unless you dont like that nice turbo dump sound)


Thanks again for your efforts in comming to do the test and for being a tester so that everyone else may benefot going forward

Al

 

Was this an aftermarket 02 comparison or stock to modified aftermarket 02 housing?

 

Honest test, honest gains!
