Re: external wg
I hope you are right.
My wg flapper sticks. OK for a couple of days after using GM lube then starts sticking again. Rather then temporarily fixing the wg flapper, welding it shut and installing a external seems a better route to go.
Can anyone say for sure that a external WG is OK in Stock Turbo class?

Re: Stock turbo class turbo mod question
There are too many loop holes in the Sy/Ty "stock turbo" class rules,, you can do a lot of mods & still run in the stock turbo class. :2cents:

Re: Stock turbo class turbo mod question
We do have some options. 3" downpipe, open exhaust, bigger fuel injectors, external wg appear to be OK... What else?
Stock Turbo
*Any Tire Allowed
*Stock type leaf rear suspension,No traction bars etc. Fiberglass springs,lowering blocks permitted.
*Any trans
*Front suspension-any
*Stall converter is permissable.
*AWD
*Stock manifolds No headers
*Stock TD06-17 turbo with stock 8cm exhaust housing
*Stock unported heads must be used. If L35s are on the truck, they must be unported, and the owner must
provide documentation from GM that this truck was delivered with L35 heads. *SyTy Intake manifold
*Engine internals, cam, etc, must all be stock. Production block with wet sump oiling.
*Stock upper intercooler, no restriction on rest of system
*Alcohol/water injection as anti-detonant permitted.
*No NOS
*Stock ECM (injector driver mods ok)

Re: Stock turbo class turbo mod question
You can use any kind of fuel.
Lightweight wheels ,brakes, driveshaft,& so-on
Special valve job to get peak flow numbers.
How about stock acid dipped cylinder heads? No porting there?
Do not even need an exhaust system, a dump pipe is fine.Port or extrude hone your exhaust manifolds.
Transbrake.
Clamp your rear leaf springs.(not a traction device)
Front end limiters.
Heads can have bigger vlaves.
Easy to build a "cheater engine" Cheater turbo,clip the turbine wheel for more top end, no one checks. No tear downs = nothing to worry about.
This list can go on & on!!!!
Just off the top of my head.
3500lbs w/driver? sounds a little gutted??? Do they even weigh your vehicle @ KC????

Re: Stock turbo class turbo mod question
Still sounds like your a bit bitter about the whole ordeal.
Just like with the big fiasco around Roberts truck. Do you guys think people are really going to stretch the rules just to win less than $200 in prize money?
IMO the rules are there just to give you a good guess at who you're running against. The person that cheats and goes around them is going against the spirit of the competition, and has to live with that. This is a tight, SMALL community and event not a huge NHRA National event. We should all treat it as such, and keep that in mind while prepping our trucks.
If you want to go through the hassle of taking your stock heads off, acid dipping them,and doing all the re-assembly for that extra .05 in ET. Go right ahead, nobodys going to check you. Nobodys going to ask you to tear down the motor for inspection. Most likely we'll all stand around, congratulate you on a good run, and you can be the one that feels like an ass for "cheating" or using loopholes.

Re: Stock turbo class turbo mod question
IMO The biggest gains in the stock turbo class are going to be from running more boost, Alky Injection, 3" Downpipe and Custom Tuning. Other things that you can do is better boost control, removal of weight (spare tire, jack, ABS, smaller battery), working on the launch (front end limiter, stickier tires), & higher RPM stall converter. Besides a few other support mods (fuel pump, ic pump, adjust fuel pressure regulator etc.) everything else that is 'legal' is going to be diminishing returns, you be better off putting you money towards a larger turbo and compete is Super Stock Class.
IMO The intent of the stock turbo class racing is a competitive low budget racing.

Re: Stock turbo class turbo mod question
Looking forward to 2007 Nats. Missed 2006. In 2005 overheated tranny and messed up parking brake system during practice so never competed in the actual races (note to myself: tranny cooler is mandatory and Syclones do not like parking brake launches).
Agree with you regarding the low budget. I tend to reuse parts that came off of my Ty (which has probably been in just about all of the classes at one time or another). Most likely (if my 100k stock turbo is still in OK shape) will try to fix the stock wg flapper or install a used external wg that I have.dgoodhue said:

Re: Stock turbo class turbo mod question
Since I know where this is directed and at who, I only have 1 respond.
The truck/owner/mods in question have been VERY public on what has been done. Nothing is hidden. The syty nats rules are guidelines and if they were specific to the degree you mention we would have 40 different classes.
Now the truck in question has had mods done, and NOT done to keep it within the rules. Every year it goes to nats, the syty nats tech has certified it still fits the class.
Cheating to me would involve not telling someone the whole story about something or hiding mods or trying to conceal them.

Re: Stock turbo class turbo mod question
Nobobody said you guys are hiding anything.
40 diffenet classes,,,,, that's a little out there.
Quote"Every year it goes to nats, the syty nats tech has certified it still fits the class.
"
And every year it seems to have more mods/loopholes found & added @ your convienence.
You guys set the standard I guess for stock turbo class ?? What is allowed & what is not.
Now your saying an external waste should be OK, I bet it will be OK.,,,,,, Who's going to argue w/you???
Now don't take this personal, I know it's just for who can have the fastest stock turbo.
So don't take it the wrong way!!!!

Re: Stock turbo class turbo mod question
Frank asked the question, I answered. NO we are not running nor plan to run external, although I do think it has some advantages over internal we have not taken advantage of.
In terms of what mods we have done, etc. In the end we tell everybody and just enjoy pushing things to the limit with what we have done. I also sit here and try to help everybody else tune and take advantage of the mods they have done. I want everybody to go fast.

Re: Stock turbo class turbo mod question
I know what you said, I am just stating I bet you could show up w/an external wastegate & the tech guys are going to allow it ,because in the stock turbo class rules it does not mention anything about that,,, correct?????

Re: Stock turbo class turbo mod question
If you want to be competitive, you have to step it up. The bar has been raised. Nothing is stopping anyone from taking the title this year.
It's not against the rules to be innovative and find ways to make power within the class.
Just an observant point of view.
