The R07 head takes a head bolt out of the intake port (as in the previous SB2 head – which had to be plugged) and has improved coolant circulation already cast into the head instead of having to being added on via external lines.

Bottom line – how much more power does it make than the SB2? No one is officially saying specifically (of course), but it must be impressive for all this redesign (and retooling) effort by the factory and the R&D by the Cup teams (Hendrick Engines, DEI, RCR). The most I could get out of one of my Chevy engine contacts was that the HP gain is “significant.” Importantly, race engine reliability and efficiency has been improved – meaning the engine stays at best power for longer.


$2,000,000 For A Dyno setup?

This is the latest number I’m hearing for the price of buying and installing and getting up to speed on operating the latest and most programmable eddy current engine dyno being used in Cup shops. Joe Gibbs Racing was one of the first to get an AVL-brand programmable dyno – according to some Cup engine builder buzz – a year or more ago. Penske Racing is supposedly next in line to have one working.

The breakdown? It supposedly it took $1,000,000 to get the dyno equipment, and another year and the rest of the money to get it installed and people trained enough to make it a useable test instrument. The unit does everything but part your hair I suppose – it can be set up to simulate full race conditions and RPM and loads so you can fully test an engine without taking it to a track and have it in a car.

Just as the 7-post (see photo – your eyes are OK) chassis rigs have made it possible for teams to program and test a chassis/suspension for a specific racetrack without leaving the shop, so has the engine dyno progressed. So, NASCAR, limit all the track test dates you want. The big-buck teams will get their cars 95 percent in tune before they ever get to the pit areas.

 

Will Dale Jr. Stay Or Will He Go?

The Dale Jr. / DEI contract negotiations continue and the influence of ace negotiator Max Siegel may be bearing success. One contact told me on the down-low that the 51 percent (or majority ownership) that Dale Jr. requires to stay with DEI has essentially been negotiated – agreed to by Teresa Earnhardt. But that she, in turn, is requesting that an independent, impartial review board be set up within DEI that would take into consideration and review any major operational changes that Dale Jr. would want to take place – acting like a board of directors it seems to me, with Dale Jr. basically reporting to it. So far, this has been balked at – but stranger management structures have survived in the business world. All parties say they want to have the contract resolved by May, so with April half-over, it’s crunch time.
