New Dyno from today 512 RWHP & 430 RWTQ SAE!

Recommended Posts

As most of you know last month I dynoed my Esprit and got 494 RWHP and 406 RWTQ SAE (502 RWHP STRD)

The car made Grate power threw the hole power band despite the "red" ECU's crazy rich A/F and my water/meth kit making it even richer. The A/F would drop off the charts past 10 to 1 and would stay that way till after 6000rpm were the stock injectors were past maxed out and the car would start to lean out and the car would get a power surge and power would climb even more.

Well from that time I installed a APEXI Super AFC-2 fuel controller allowing me to tune the fuel curve. Well let

Upgrade today to remove Google ads and support TLF.

Matt,

These are great numbers! Keep us posted! Looking at your A/F on the last dyno sheet it looked like all of that extra fuel was costing you a fair amount of midrange torque. How much of the increase do you attribute to the HKS ignition mod?

Thanks,

Some of the results

Peek TQ on the "red" tune 406 RW at ~6300rpm

Peek TQ NOW with the new tune 430 RW at 4400rpm

TQ now has gone up by 50-60 ft/lb from 4200rpm ~6000rpm

HP hits 400 RWHP now with the new tune at ~5100rpm

HP hit 400 RWHP with the "red" tune at 6000rpm

All the overly rich power "dips" and spikes are gone, power is linear now and silky smooth.

Very impressive figures again Matt.

Can you mention which engine sensors you upgraded to compliment the mods you have made?

Cheers,

No real way to tell, I installed it and the AFC on the car at the same time.

Did you not upgrade the MAP sensor?

What boost are you running now?

<{POST_SNAPBACK}>

Still on the stock MAP sensor for now.

On the boost, I'm running 18psi. On the Blitz DSBC electronic boost gauge.

Before installing the DSBC on the car I had 16psi Waist gate Actuators on the car being allowed to be controller by the cars stock boost control. I had checked the boost back then one time buy running a boost line in threw the window hooked to a cheep Automeeter boost gauge and according to that I was getting just shy of 17psi. But I did not really trust that boost gauge.

So out of curiosity I hooked up the DSBC boost line to it so just the gauge would work and boost control was back in the hands of the stock boost control, and the actuators that opened on a hand pump at 16psi. Well imagine my surprise when I ran the car and the DSBC logged 19.8psi peek boost. This is were the boost was when I Dynoed 494 RWHP SAE with the sub 10 to 1 A/F.

This leads me to believe that the Stock boost control has a problem controlling boost with up-graded turbos, and Actuators set that stiff. After seeing that I believe that a good electronic boost controller is a must when up-grading turbos and actuators. Or maby it wasjust my car

Do you understand how the AFC works? It allows you to alter the out coming signal from the MAP sensor before it gets to the ECU. Up or down.

Also the car runs so rich as it is, it can use added air/boost past were the MAP is maxed out that helps to lean the car out.  Threw the RPM band at 18psi I am leaning it out with the AFC from 11 to 16% depending on the RPM to get the 12.0-12.1 to 1 A/f with the MAP being over run.  Now turn the boost down to 15psi (or 13psi for that matter) with those same AFC setting and the A/f drops to 10.9-11.1 to 1 .  see how that works?

So as you can see you really don

there is the pulls on a split graph with HP on one and TQ on the other comparing the 2 runs, (the 494 RWHP from befor the AFC, and the 511 After the AFC)

here is the latest chart by it's self

Matt,

quick question: When you installed your wide-band 02 did you have to add another bung or were you able to remove one of the post-cat o2 sensors without tripping a code in the ECU?

Thanks,

I used the right side rear o2 bung. Yohans ECU removes the rear o2's from the ECU

Up-date, to all those that thought "the stock motor will never last at those power levels" Well I have been driving the car at those boost levels and even a few trips to 20psi every time I drive the car. Still running like a champ not even a hick-up.

These motors are allot stronger then people are leading you to beleave. Just stay away from detonation and thy hold up just fine. As soon as I get some time I m going to be installing some 310cc injectors in my quest for 550+ RWHP

Those who say it cant be done are most of the time interrupted by those that are doing it.

"IF" thy are real? I guess posting the Dyno charts, and a video of it does not prove thy are real? Heck the name and phone # of the Dyno shop in El Paso I dynoed it at are printed on the top of the Dyno chart give them a call.

Or better yet fly in over here and I'll give you the ride of your life. Care to put your money were your mouth is?

On a side note do I think the transmission will last if I power shift this car? no I do not that

Well thats the same Dyno that my 400 crank HP LS-6 CTS-v laid down 326 RWHP when stock, and 482 RWHP with the supercharger and other bolt-ons on it running 9psi of boost.

And My buddy's 2003 Corvette ZO-6 with a TTI stage 1 twin turbo kit on it running 8psi laid down 472 RWHP the SAME DAY that the lotus layed down 511.5 RWHP.

LEW loves the Esprit modification scene and it's great to hear about all these mods that give the Esprit more power. But we do agree with Mike a little. We don't really want to see engines blowing and reliability issues.

The Esprit hasn't the best reputation with regard to reliability and pushing huge amounts of power through them without upgrading basic components is always going to cause problems.

LEW's Esprit has suffered from increase power, with new bottom-end bearings needed due to running increased boost. Luckily it was caught before any failure.

We would suggest using your modification inline with component improvements to create a fast and reliable supercar. Remember the Esprit is about so much more than straight-line speed.

Please read our guides on with engine power and gearbox testing. These should help you with regard to your quest for more power. This guides are from Lotus own facts and figures. There's also a guide to the gearbox upgrade, which you might need in the future.

We would welcome your modified Esprit on our Owner section, as I'm sure most of your modifications would be of interest to many Esprit owners.

Keep on pushing the boundary, but look after your Esprit.
