Turbocharger in Super Street???
 

I want to run my turbocharged slant-six Valiant in Super Street, but according to this, from the NHRA 2012 rulebook:

SUPERCHARGER, TURBOCHARGER
Permitted only when racing gasoline, gasoline, diesel, or alcohol is
used as fuel. Restricted to standard Roots-type, centrifugal, or
OEM-type screw supercharger.

It would seem I can't.

You know they always say, "If we don't say you can do it, you can't."

Well, nowhere on that Super Street rulebook pages does it say that turbochargers are legal in that Eliminator.

Are they??

Has anyone ever seen a turbocharged car in Super Street at an NHRA points race or national event?

Screw-type positive displacement blowers are specifically allowed, but what about turbos??

I'm confused...

Any information would be greatly appreciated!

In div 3 Jack Roush's daughter ran a turbo car in super street. And now there's a honda that runs a turbo.....

Thanks, Bob; I appreciate the info... The rulebook seems self-contradictory to me.

Its always great to think outside the box and try something new, but Do you think you will run into any problems with turbo lag and leaving on a pro tree???

Re: Turbocharger in Super Street???
 

Spool up time will definatly be an issue on a Pro tree.
Not that anyone in the opposit lane would take advantage of that !!
Like the car that Kurt Bush ran at the Gators last year , it might be fun and it certanly will be an interesting car,but in the end it's certanly going to be extremly difficult to be competitive with it.
I'm not certain, but I believe with the turbo in S/ST ,you will need SFI pants and gloves as well as the jacket.

I always thought it was "If they don't say you can't then you can" until the next rule revision.

I believe the Honda in super street has a roots type blower, and the Honda that team runs in comp, has dual turbo"s.

Wasn't real sure, just know he spends a lot of time getting staged...

Re: Turbocharger in Super Street???
 

Yes, that would be a major consideration, but with a trans-brake and a high stall converter, the spooling might not be a problem... but probably would.

Turbocharged cars are problematic, to say the least, when it comes to dialing one, but this was just a (probably BAD) idea I had, since there is no place in Comp Eliminator for the car... I was just thinking... (not always a good thing... )

Thanks to everyone for all the replies!

I knew a guy who ran a turbo street-driven Camaro in SST back in the late 80's. I know a couple of people who have run turbo diesel pickups in SST. I plan to run SG or SC occasionally with my new truck I am building (turbo diesel pickup).

I am pretty sure the rule is just laying down restrictions for the superchargers, and effectively is NOT restricting what type of turbos you can run. However there is a section in ET and general regs that increases the firesuit requirement for turbo or nitrous cars without an OEM or 0.024" steel firewall.

Thanks, Michael!!! Good luck with your project!!

bill, i ran a twin turbo small block 69 camaro in super street from 1995 till 2001 in div 6, never had a problem in tech. bob munoz

Hey Bob, how's it going? I was referring to Ramon's Camaro above, but I knew you had run one as well (but I never saw it since I lived on the East Coast during those years). Don't know if you remember me, I have the "Student Driver" Super-Gas Vega. What ever happened to Ramon? Remember when your brother and I used to bet a $1 bill on round wins when we ran head-to-head? I still had that $1 bill until a few years ago. How is he doing these days? Sorry to derail a thread, but haven't heard from Bob in years!

Thanks Bob!

I do appreciate the input!!!

You may want to investigate the launch control that the Pro Mods use cut good lights on a .400 pro tree. As I understand it, it's much like a 2-step, except that it retards the timing so much that it causes an explosion of un-burnt fuel in the header tube. The force from the explosion spools up the turbo in less than half a second.

Re: Turbocharger in Super Street???
 

Normally, the anti-lag you're referring to requires timing at about 40 degrees AFTER tdc. You could try stalling the car in second gear with the transbrake button held down. The brakes should be able to hold it at full boost and the transbrake won't operate in second gear. When you're staged, put it into low to activate the transbrake. The transbrake will hold the car since the brakes won't in low. Just a thought.

There's also a device that delivers an adjustable pulsed signal to the trans brake solenoid. When activated, it allows the car to creep forward slowly with the trans brake applied and the car at full boost. Might be hard on internal trans components though. Good luck!

This is what Bruno Massel uses to spool up rapidly with his world-champ turbo car in Comp eliminator. His father's customers are mainly in Top Dragster and other fast bracket cars with a torque converter.

About one paragraph up from the bottom is the phrase "Now Available - Dual Stage Pressure Assembly for turbocharged power plants that allows for ease of "Spool up"!"
