Going beyond 7k RPM: A Thread

[hellasf1]

Yeah. I don’t shift by shift light. I shift by engine feel and engine sound. And the v6 pulls even harder those last 500rpm so it fools me into staying in throttle too long and I end up banging against that limiter.

I bet if you raised the limiter the engine wouldn’t nose over till around 7200.

It’s like they left the same cams installed that were for the Evora and just imposed a shorter redline.

Yea I have a JUBU tune with the 7200 rpm and it’s perfect! Stock always felt jt cut short and it definitely has more pull upper rpm’s. I’ve yet to hit the limiter with the 7200 set up. I think that’s perfect and safe increase. You can go higher but would require new parts and lots of labor cost I think 10-12 hour job.

So, JUBU tune to 7200 redline and the JB4 to boost power further. Is this the perfect combo (with a careful eye on the axles!)

I have the JUBU 440 so it increases power no need for the JB4. I’m going with the 460 kit soon with JUBU.

JB4 wasn’t an option when I decide to increase power and RPM. Will be interesting to see that. I will be doing dyno with the 460 kit and will post updates on the JUBU forum I have.

This car blew the engine with a Jubu 460 kit.

The car has been sent to Jubu in Austria and they did the replacement at their own fees.

I know this car has been tracked pretty seriously so that means if you raise the power and beat the crap out of it wont last long.

We all know the Toyota powertrain is not as bullet proof as we would like to.

Yeah you never hear these stories.. its pretty quite here with regards to Jubu. I have send mine back as it was not acting to promise.
