Re: 2002 Lotus Esprit V8 TT build

Sorry for not posting for a while everyone.. The engine is now rebuilt and back in the car. I had to get some technicalities with the business taken care of and my baby sister came over from Denmark (who I haven't seen in 5 years.) I will post some of the progress pics when I get a chance -- I have to work on it every night this week to finish, so I likely won't have time to upload much.

Re: 2002 Lotus Esprit V8 TT build

Okay, so here's a progress update: Basically, I replaced all the bottom end bearings and gaskets, had a tool made up to set the timing chain tension, plastiguaged everything, re-assembled and installed the engine. Here's a very brief photo/video list:


bottom end assembly:




Engine ready to go in:




Engine landed on the mounts...




Harness partially routed:




Transmission in:




Intercoolers in:




Ready to rock!




And.. here's a clip of it running (don't worry.. i warmed it up for a long time and then checked for leaks etc.. before I gave it a couple of shots of gas.)

Re: 2002 Lotus Esprit V8 TT build

So... The results from the dyno are basically this (from stock 295 ft-lbs of torques and 350hp): 430 ft lbs of torque and 430hp (actually it was 428). The car produces over 400 ft-lbs from 3500 rpm to 5800 rpm, and the hp is over 400 from about 5000rpm to about 6200rpm. I did some testing yesterday in +35 celsius weather and with a limited slip diff and 295 wide tires... the car breaks loose in second gear and fish-tails a bit as it struggles for traction. The Intake Air Temps on the dyno never exceeded 58 degrees under load, so the intercooler efficiency is perfect. The car actually pegged the dyno on one run -- 450 ft lbs of torque, but we dialed back the boost a bit so that we didn't deliver that much again. I will post the dyno sheet and the video of the pull when I receive them.

Re: 2002 Lotus Esprit V8 TT build

Re: 2002 Lotus Esprit V8 TT build

Okay.. here's a picture of the dyno screen.. fairly blurry, but you can decipher what you need to. I am still awaiting the arrival of the original .pdf or whatever they use to show the graph.

Re: 2002 Lotus Esprit V8 TT build

IT's bordering on ridiculous... I know there are far more powerful cars out there.. but it's wild to drive an Esprit with that much power. The Esprit was never meant to be this quick. They are usually really good handling cars that are moderately quick... this thing is now crazy quick and it handles significantly better than factory (as there are coil overs and LSD and huge brakes on it as well)... It's nearly nirvana... I can't explain it really.
