Hello, just wanted to give you guys a peek at what has been happening at Esmeril Racing over the winter.

I know it is not an RX-7 but it is an RX-* and it is a single turbo. We previously reached 414whp on Pump fuel with one of our "out of the box" turbo kits (t04s equivalent) and ignition upgrades. Now we hope to reach 500whp comfortably on E-85.

The engine has our new Apex seals, has been ported and dowel pinned by us. It has a fabricated aluminum intake manifold with a calculated plenum volume, a water to air intercooler system which has about 50% of the volume of the original FMIC setup to help reduce lag and compensate for the large turbo. The turbo is a Precision Turbo PT71GTQ with a .96A/R (funny how it boosts by 4000-4500rpm ) and the exhaust is a completely fabricated 4" full from the down pipe back. We built a one-off 3 into 1 exhaust manifold for this (the manifold included in our kit was designed to peak flow at about 420whp)

It is running on E-85 using dual Bosch -044 fuel pumps with an Aeromotive FPR and a 1/2" feed line from the pumps to the front using the stock fuel line as a return. It has 720cc primaries, 1680cc secondaries and 1000cc primary 2's in KGparts fuel rails with -6an lines going to each rail. The clutch is in the process of being replaced with a OS Giken twin disc.

This was just for fun and to prove the industry wrong about the RX-8 .

We plan on taking our time tuning and testing everything carefully and slowly so when we have figures we will post them but I have no idea when that will be. Most of the tuning will be "street" tuning since this is meant to be a street machine. We plan to take it to the strip if we have a chance.

Thanks for looking and enjoy!

Best regards,

What are your thoughts on some of the side seal problems I heard people have been having when they really push the Renesis?

 

No pics when you click the link.

 

From my experience...once you replace apex seals the next thing to go is side seals this is mainly due to the fact that the Renesis is more prone to detonation due to its higher compression rating. However, the side seals have very little exposed area to the combustion so it takes a good amount of detonation to break them. Simply put, if you don't detonate they will hold fine at least to just shy of 600whp. I haven't tested or seen them tested above this number. We switched to E-85 when we decided to go above 450whp and that pretty much took care of the detonation for us...unless we commit tuner error and advance the timing too much. The renesis just needs to be kept rich and with conservative timing because of the higher compression but it is capable of reaching nice numbers.

Best regards,

Chris

 

Sorry about that:

What are the measurements on your intercooler?

 

The core is 4.5" thick, 4.5 wide and 12" high. The overall dimensions of the intercooler are 12.5 high by about 12.0 wide by 4.5 thick. The inlet and outlet are 3" and are at the top of the intercooler (it is shaped like a V where the bottom of the V is about 7" wide and the top is 12".

Let me know if you need to know where to get it, I got a really good deal on it and its worked great.

Hope this helps.

Chris

 

very cool.

i've got family in plymouth MN, love to check this out in person sometime...

 

Very cool. I really like seeing turbo'd RX8's as there is only one around here I have ever seen/heard. I believe he was putting down about 350-375ish (don't remember).

Your setup is very clean. Very nice...

 

Would love to see new stuff from chris!

 

I like the intercooler setup.....
how long have you had this air/water setup, and how stable are the temps in normal driving and boosting?

by the end of the year im going to put an I/C on my FD but after looking at your setup, im wondering whether to go large SMIC or your air/water setup..... very interesting to say the least.
Im staying stock twins

 

god its sexy i wanna do the same in a rx8 some time too

 

I thought he was swapping in a 13B-RE...
