External Wastegates

[smallv6]

Who makes the best External Wastegate that would be a direct bolt on to my ATR Downpipe (Replacing ATR External Gate)
Also where could I get one.
Thanks

I looked into the HKS waste gates as replacements, but they will not bolt directly up. I will check into the Innovative gates and see if they are direct ATR replacements. If you are interested, Email me and I will get a price on the Innovative stuff for ya. ERIC.

I think this is one of the best one out there http://www.srmotorsports.com/Tial_Wastegates.html

But I also heard good stuffs on the Deltagate or the Racegate.

I have been using and selling the Turbonetics, racegate and delta gate. They work great and offer the best bang for the buck. The deltagate is rated to 400hp, the racegate is rated to 1000hp. You willneed an upgrade on the DP if you need a racegate.
hope that helps,

I use a deltagate on my atr pipe

never had any boost problems

 

[ross87t]

I used a Deltagate on my previous Buick. I never ever had a problem with boost. It was always perfectly stable.
Also, I had it mounted on the crossover pipe. Talk about loud at wide open throttle!

That's where mine is mounted. It does tend to cause some heads to turn.

Good info on the most up-to-date WG from HKS...50 & 60mm.

You'd need a new, larger flange if you'd previously had the ATR WG on your 3" DP.

(Need to shop that price around)

Racegate price is $395.00

Does anyone dump the exhaust to the atmosphere? I'm debating on whether I need to run it back to the dp or not? How loud is it ? Is it louder than driving around with the cutout open.

Yes.

For the various Heads Up classes at the GS Nationals, it is a requirement.

How loud is it ? Is it louder than driving around with the cutout open.

Mostly the same, however, Deltagates on the crossover that are vented to atmosphere are what are generally known to give you the "chainsaw on acid" sound.

 

[trading t/a]

If you are ony venting one side of the engine(1,3,5) wouldn't that cause a problem and still let 2,4, and 6 still spin the turbine? What are the shortcomings of a setup like that. I have the the provision on the turbine housing to mount the gate but wondered if the exhaust gases venting into the engine bay would burn stuff up.

That wastegate will not fit without making huge changes. Here is a comaprison of the HKS GT Wastegate. The GT is the same size as the GT-II. They are made for 400-1000+ HP. I would use their smaller gates like the HKS Standard or the HKS Racing. I can get any of those gates for a good price. ERIC.

I can get anyone that the GT-II for a lot less than what is on WOTM.com can. Email me Eric@bnecustoms.com for price. Thanks.

We run the racegate on the cross over for the 85 and it works great.

****(The installation of a GT-II requires only the installation of either a 50 or 60mm flange.)****
========================================

The GT is the same size as the GT-II.

****(The GTII is physically smaller and lighter than the GT. The GT-II comes in 2 flange sizes, 50 & 60mm.)****
========================================

They are made for 400-1000+ HP.

****(Sounds about right!)****
