The title says it all..
We don't have any bone stock cars here and I have been working on a new throttle body that bolts directly to a non modified L jet or D jet plenum.. I'd only need the car for an afternoon, so hopefully someone in Atlanta or the surrounding areas can hep us gather some data on my chassis dyno.. The engine must be in a good state of tune, not worn out and not filled with "bugs" and issues.. We need a solid before and after comparative to polish off this developoment and get it on the market with known results. We have the bigger engines covered and don't need any test cars for those. A 100.00 Gift Certificate from my store will be awarded to the two people that help us out... Wait till you see this... Up to a 48mm taper bored throttle body that bolts right on in about 20 minutes! |

We made these for larger displacement engines that are still using the stock plenum...
A 52mm unit may be available and bolt right on, but what if thats too big??? Bigger isn't better, especially with T/B sizing due to lean out at low speeds and "tip in" due to "big throttle body syndrome". My intent is to see if this unit is compatible with the stock FI and offers any gains in torque, HP or RPM range so I can thoroughly understand what the unit does and effectively answer the questions of buyers that inquire about it... Thats what I do. The unit could hurt the performance of a stock engine and thats what I need to see comparatively and back to back with my own two eyes in my environment... If the unit helps performance we need to understand why and gather data to support this exploration. The units we are using were made application specific and can be sized in 40,42,45,and 48mm with either straight or 5* taper bores. The stock air filter or a high volume foam filter is compliant with these units. The stock throttle cable also works. Like I said, these were made for our larger displacement engines and the unit I will be testing was particularly sized for my 2056cc-115 HP engine that is designed to utilize stock D or L jet FI. I feel the RPM of this engine can be improved upon by a slight boost in throttle body volume. I just want to see how the stock engine responds to this as well and lay the graphs over each other for a direct comparison and understanding. I am doing this testing objectively and no matter what I may think we must at least try the component and allow it to illustrate the big picture... Those who don't explore never get anywhere.
