How Much Does The Stock Elbow Hurt?

[Blown&Injected]

I did a search and did not notice results for over 10 years...I did see everything from just a little help to big gains for just switching out the elbow.

I ported the stock elbow and have a 3" DP that I was just about to mark for a WBO2 bung when I got to thinking - should I invest in this DP if the ported elbow is hurting and a new 3" without the elbow would be a much better part to go with.

It is a (roughly) high 11 car with thoughts of some type of new turbo such as a MFS620 or a PT62...and mid 10's.

So, is it foolish to continue with the current 3", two piece, stainless steel DP?

Cars in the former TSA Class (Totally Stock Appearing) have been +120 mph so, I wouldn't think it's a major restriction on a high 11 car. Obviously, very few know what was done to the elbow. . . . . .

About 25 or more years ago with a stock GN, a 3" TH downpipe was worth .2ths in the 1/4 mile, should be more with a larger turbo.

Put a 3 in dp on it and call it a day.thats a part that wont hurt you on a 11sec combo and you can take with you on your mid 10 sec journey.no you don't need it at your current power level

If I can get 2 tenths for about $400...Sounds like a good deal. The best tuners I am sure can do better with what I have, but I would be happy with 2 tenths.

What I mean by roughly high 11's is that I have run 11.7, but it was a first time out and there was no tuning beyond raising the boost to 22 PSI and fill the tank with Sunoco 100 unleaded.

That's pretty darn good. I say chuck the wb on and try some more tuning. You can use the wb on the new pipe next year.

My stock elbow hurts every now and then but today both of them are doing alright(LOL)
