Turbo Stockers

Jimi B · 11-23-2009, 10:57 PM

In the 2010 rules amendments they have added for turbo stockers:

Quote:

Turbocharger size will be verified by measuring the housing bore at the leading edge of the impeller wheel. The maximum diameter of the housing bore at the leading edge of the wheel may not exceed 2mm more than the maximum allowable turbocharger size
permitted.

By housing bore do the mean the inlet of the compressor housing? And they are measuring the id of the inlet right in front of the compressor wheel? Just making sure I am interpreting this correctly.

I doubt they know. When they did mine they never had a clue. Even though I gave them a turbo to measure. and count vanes etc. The next time I came apart. They had forgot about it and didn't do a thing with it. It was a junkyard unit with a lot of play. But the exact same as the one I had. They were more obsessed with my piston being .375 to high (LOL).
A mistake in their books, which eventually was corrected.

PS If all they are going to check is size. I can make a stocker run 3 seconds under Every turbo car I know runs a stock turbo. not a "stocker turbo". If you cheat a turbo on some cars you would fly. There is a lot more to a turbo other than how much boost you can run.
It's more about how quick you can get the boost.

With the stock turbos that shouldnt be a problem! Getting the boost the same every pass to actually win a round is the real challenge!

My car used to be consistent. The only problem was the nut behind the wheel Some people went rounds with turbo cars.
If you think about it how many consistent number 1 qualifiers go rounds? Whether turbo, supercharged or naturally aspireated

If they are clueless about "size" I bet they will have fun with altitude et/mph corrections for turbo and supercharged sportsman cars.

Prior to this rule the only turbo rule I have seen in stock is the header rule. Header permitted, turbo must remain in the engine bay. Art, do most or all the turbo dodge guys run the stock exhaust manifold?

Guys, if ya don't mind I would like to join in on this conversation. I have just started running an '88 thunderbird 4 cylinder turbo car and would love to ask some questions. I'm an IHRA car in I/FIA but could fit in H/I/J with weight.

1.) Assuming you are using a two-step, what rpm are you able to leave at?

2.) How much difference, if any, have you noticed with engine temperature being higher or lower in your et's?

3.) How in the heck do we figure out how to dial these things? I have noticed if we are running pretty close my car seems to fall off .05-.10 every pass. Is that pretty normal?

Thanks for any help

People tell me to just put a small block in it and forget this turbo stuff. But, I do like a challenge!

Sounds like your having an electronics issue. You can not fight the computer, you have to fool it

What brand of computer are you using.

Don't fool it, just reprogram it!
