Wastegate? to downpipe or atmosphere??

[crapr6]

Hey guys whats up, What do most of you guys do running turbo's with the wastegate. Do you guys run it back to the downpipe or just let it vent to the atmosphere? Just wondering what most of you guys do. thanks

1.3 Exhaust
EXHAUST: All entries allowed to use tubular headers. Adapter plates permitted to bolt headers to cylinder head. Exhaust must be directed out of car body, away from driver and fuel tank. All exhaust gases released from engine must pass through entire exhaust system.1.3d) MUFFLER REQUIREMENTS: Commercially available (generally available through retail locations) mufflers required. A maximum of two (2) mufflers is allowed. A maximum of one (1) inlet and one (1) outlet is permitted.




I hope all the DR turbo guys show up in GA. with their waste gates dumping through the exhaust system! Remember the suprise inspection the blower guys got in Fla. Also hope your mufflers are legal. :eek:

Thanks for the info, Iam running a single 4in exhaust using a Dynomax Bullet muffler. I havn't completed the downpipe/exhaust system but most likely tring to get it to exit out right after the frt tire, but may have it end infront of the the rack and pinion due to space..

p.s. what happened in Fla to the blower guys??

To answer your question. Some people say if you put the wastegate back into the downpipe it will cause turbulance, that is why they dump it seperately. If you dump it seperately it has to have a muffler and would be considered dual exhaust, which is part of your exhaust system.:)

The picture is the really small muffler Burns makes. There are a couple of that type available from different manufacturers.

Just Off the phone with head of tech. :D ;) No worries. I put my hand over the spout off the waste gate and i dont feel any exhaust.:D

i was told someone else made a muffler similar ut dont know the names, he burns is a little rough on price

I dont think thats gonna slow down Johns reaction time:eek:

Behind Bars Race Cars makes a real nice aluminum muffler. I have one of his 5" models, I forget the part number. I don't know if he has them listed on his web site but if you call him he can take care of you. I don't think they are quite as pricey as the SS ones either.

Great info, thanks for the reply. I might just go with dumping the wastegate seperately with a small muffler.
thanks

i guess i'll put a muffler on my wastegate, maybe i'll make alittle more boost, hehe. just kidding. i have a question though, why would the 2nd quickest car in nmra drag radial history care how our (turbo) exhaust is routed? you have "us" covered by over a tenth. the closest turbo car has be 8.29 (john k) and that was made BEFORE quallifying.
i happen to have a muffler, a "TURBO" muffler. my particular brand comes from precision, but innovative and tubonetics as well as a few other companies offer them as well. my exhuast (db) is very quiet and is also very restrictive, whanna compare backpressure? if my muffler is in question maybe TECH can chim in??
the way i look at it, i have a set of headers, a single exhaust pipe, a turbo muffler, and a single 5" tailpipe. i could see the question of the wastegate, BUT you first need to "PROVE" that it dumps exhaust while going down the track. i KNOW for a fact mine is closed while going down the track. but then again, wouldnt the wastegate itself be a restiction ( hence a muffler??). in that case, would it matter what you do with the wastegate because IT is a muffler, in which mine happens to be a tubonetics.
i think this is absolutely pointless because your combo as well as others has the least restriction. yet, we have questions about the turbo cars exhaust? to me that sounds like a low blow, you ran a turbo and know the drawbacks as well as the benefits, if there were more benefits you would have stuck with the turbo.
IMO, we (hop & ct) are down like 2 flat tires (you like that, huh? lol) and i'm just voicing my opinion. i quess the question needs to be, what is a muffler? INMO, i have 2. my main--, precision muffler, and my turbonetics-- secondary muffler.
i have a very good and logical suggestion, if there is a muffler rule why dont we a have DB limit? that would limit/elimitate the STRAIGHT through mufflers that are curently empoyed be the blower and nitrous cars. nuff said.
heck while we're at it wh don't we eliminate the wheelie bars and really put some excitement into the "show"?

[CHRIS TUTEN]

ohh, i wasnt going to post this but what the heck, i went testing today. not much to brag about it seemed ok. 3.62, 5.42@137.5, 8.26@171.9. i dont know how that will pan out in competition but it is by far the best we have ever been in testing. i know, what was the 60'? cant we keep alittle secrecy?

[HOP]

Why is everyone getting upset? CRAPR6 asked a question so I looked in the latest rules and thats what I read! I was only trying to look out for you guys!

Sorry Chris but I don't think this is absolutely pointless, (just like you) I'm just voicing my oppinion! Also as you have said I also ran a turbo, please don't tell me your waste gate doesn't open in the first sixty feet (going down track) because if it doesn't then you should take it and the controller off the car (to save some weight) and you don't need it!

I didn't see any of the turbo guys getting this worked up when they teched all of the blower cars!

CL, did you get your engine yet? I also have a waste gate here (on the bench) and I can't feel any exhaust coming out when I hold my hand over it!

Sorry that I pissed so many off by voiceing my oppinion but I was reading through the rules and stumbled across this.

[peterc]

actually Hop, i did express a concearn for the blower guys... i didnt think you guys should have had to take your blowers apart in the middle of a dusty field... im sure procharger and vortech dont assemble them in their parking lots...

Im not pissed

:eek:
Hey guys sorry if i started something here. Just wanted to see how you guys run your wastegate dump tube. Not trying to be a jerk,but if any of your guys wastegate dosn't open at all down the track why would you even have one on your car then? Well dont take any offence to this thread guys..thanks for everyones replys.

[CHRIS TUTEN]

its ironic you mention taking the wastegate off, i tested yesterday with it closed from the start of the run. maybe with some more testing i wont need it:)
im not pissed and i apologize if my post came across like i was. see you guys in ga.

[chip provenza]

Chris I see You had a 88 to test with:D I also agree get rid of wheelie bars.By the way I run full exhaust to the axle housing with 2 chamber flows.The way I see it I still fit the new rules.Good job in testing I didnt even pick up 34.5 in the back end on my best pass damn turbos.Good luck in GA.

Thats because you went to damn fast to the 1/8th!!!!!!!!

Dam iam starting to wonder if i even need a wastegate??? but with your wastegate not opening at all what kinda boost are you seeing? I understand if you dont want to let me know the psi since this may be a secret to your weapon..thanks

The only reason he doesn't need a wastegate is because he now has a magic transmission;)

[timneagroup]

wolfe makes a waste gate muffler. Check with him before GA.

A muffler in the waste-gate area is not going to make a difference. All race mufflers by the way are a joke. A few holes in them and some fiber-glass material. I know on my car it made no difference with the muffler on or off.

i ran the same ole 85. i just got my tranny, jason's tranny (major thanks!!)and converter back fri night. the 8.26 was my 2nd pass. the 1st pass i had to pedal it and went 8.53@172.2. i only made a 2nd 1/4 pass to make sure the mph wasnt a fluke. the rest of the day was spent working on the 60'.

jason, i didnt test with your tranny. you let me borrow it for sunday@ bradenton and it wouldnt have been right for me to put any uneeded passes on it. its all freshened up and ready to go, you still going to ga?

crapr6, i had 8lbs on the start and 20lbs 1.1 sec into the run. best 60 ever but still not what the blower cars have been able to produce. i make 19.8- 21lbs on the top end depending on the weather. boost isnt the secret;) the only bad thing is the track i test at is way better than reynolds. i probably wont get to use that info until we race on a better track.

Thanks for the reply, i see about boost not being the secret now, but i would have figured the turbo would be producing alot more then 20psi without the wastegate opening? Well thats why you guys are so dam fast, not just because of boost, but the over all package..goodluck to all you guys.
