Anyone have more info on the 3rotor renesis??? That thing sounded amazing screaming by on the track!

 

it not a renesis its a 20b

 

and to think the sanctioning body has told them to put a muffler on that thing

 

Do they represent it to be a 3-rotor RENESIS, or do people just assume that it must be? Does Mazda support them directly, or is this a junkyard Cosmo or bastardized block?

 

Mazda does have official support behind this effort. It's a 20B with some RENESIS internals... So it's RENESIS *based* in the marketing scheme!

I took off early Saturday at the ALMS race at PIR. Where did they place?

 

2nd in P2 class, 18th overall...

-Bern

 

Can you tell me what RENESIS internals it has.

 

how many cars in the P2 class at that race? please don't say 2 Bern!

The race from sears point on tv, their car finished 3rd of 3 several laps down. 4 seconds a lap slower than P2 leader. teething and development.

I hear their 20b has Renesis rotors, they're lighter than 20b rotors. Some people are not sure there is a competetive advantage to using them. but they have 2 oil seals per side?

 

maybe a rotor and a bearing or two...

A hint to what the motor really is can be found in the last name of the co-driver

At Infineon they were coming in every 1-2 laps during practice, and qualifying, alot of teething pains to be sure. Motor seems to be real strong, the Chassis seems to be the weak link, also, the drivers are very new to prototype racing. Carl

 

Quick rundown... 3 total cars in P2 Class

P2 winner
Lola B05/40/AER
Started 5th finished 4th
132 race laps completed
Best race lap 1:06.679
Best qualifying lap 1:05.744


P2 second
Courage C-65/Mazda
Started 13th finished 18th (behind 12 GT cars)
117 race laps completed
Best race lap 1:09.311
Best qualifying lap 1:10.763


P2 third
Courage C-65/AER
Started 6th finished 21st
Fell out with a mechanical issue on lap 86
Best race lap 1:07.52
Best qualifying lap 1:05.865


The biggest issue will be the new factory Porsche/Penske P2 cars debuting at the Petit LeMans in Atlanta and also running at the ALMS Laguna Seca round in October. Here it is:

They're way off the pace. GT1 cars seem to be faster. I read on another forum that they were using a ~42mm restrictor and they've negotiated with IMSA to run a 49.1mm restrictor to be more competitive. I understand that development takes time and that they don't have much of a buget, but this seem to be a bit much.

 

I will disagree and agree with you Carl...

I disagree that the chassis is the wink link... the same Courage C-65 chassis with the AER motor is VERY competitive in classs with the Lola chassis AER P2.

I agree that the drivers are very new to prototype racing, as is the team.

-Bern

 

My bad, you are right about the chassis. I think you nailed it on the "team thing". When I met, and talked to them at infineon, they def. reminded me of a smaller effort than a standard LMP effort.

 

The results of that meeting with ALMS, are that they were given the ok to use a 53.5 mm restrictor, up from the 49.1 mm they had been using. So, hope this helps power some.

Thanks for the corrections. I should have looked it up rather than trying to use my memory.

 

Well when i was down in south carolina a few weeks ago to pick up our race 20b engine from Roger Mandeville i ask him whats the deal with that engine and he said, long story short it is not a RENESIS 3rotor. he said it is pretty much the same deal as our engine. We are running racing beat housings i am sure they a running mazdacomp housings. I think he should know since they bought the parts from him.

 

yea... I think we already made it clear that it's NOT a RENESIS 3-rotor... it's a RENESIS "based" 20B. What does this mean... you'll have to call Mazda Marketing to find out. Like I said... maybe a few of the seals and potentially the rotors are RENESIS, but not much more.

Btw, what race car are you running your 20B in?


Cheers,
