Gary came to us with a 2005 Mustang GT which was fitted with a TECHCO 3.0L Reverse Revolution Twin Screw Supercharger System and strapped down to the rollers! With a Tillman Speed SCT custom tune, using TECHCO's Low-Output 7PSI system and a Boost-A-Pump, we were able to pull out over 428 Rear Wheel Horsepower and 395 Rear Wheel Torque SAE Corrected! This was on a Manual Transmission vehicle with 3.55 Ring and Pinion with conservative timing! Great numbers and the car is a blast to drive!

Nice numbers! How much higher could you go with that kit safely on a stock bottom end?

[Tillman Speed]

No problem going 10PSI. The car will need a fuel system once it get's past this point. I think we hit right around 87% fuel pump duty cycle at 6500 RPM. We try and keep it below 90%, so I think if we had made another 10RWHP or so that would have been it for the stock pump. Other than that, no problem going as high as 10PSI-11PSI. I try and keep them below 500RWHP SAE corrected for engine longevity.

I like the idea of the dual GT500 pumps anyway. What would 10psi make at the wheels? I may also be interested in the Super Shake due to the fact I already have the CDC shaker and don't want to by a new hood. Any experience with installing and tuning that system?

[Tillman Speed]

This was a conservative tune. We pulled timing top end, left the air fuels rich, etc. I don't see any reason why this car couldn't have made 475-480RWHP all day long.

You can see this graph has a completely different curve than the 7PSI kit. With a less conservative tune, it would look just like the 7PSI kit's results only the lines would be consistently roughly 60RWHP and 60RWTQ higher.

Just wondering what your experience is with the Saleen Super Shaker?

[Tillman Speed]

We've done only a few of the Super Shaker kits. I really don't do a whole lot of Saleen, to be honest. Especially since all the guys I dealt with all moved on. I'm much happier working with Techco, Roush, Edelbrock and Whipple from a business standpoint. From a product quality standpoint, I think any of the brands I named above will surpass Saleen.

Thanks for the info
