  1. @cweeden I believe the most important part is the actual chargecooler... That would be great if we could source it... The rest of the piping, electric pump and radiator I believe we could each custom build..
  2. @mike_sekinger Fantastic video !!! Thank you !!!
  3. @mike_sekinger Thank you again for your response !! As always you provide true valuable information for all of us here at the Lotus Esprit V8 forum !! I am convinced the chargecooler is the best modification for my car.. I will try to find someone here in Athens, Greece that deals with chargecoolers that can fabricate a custom solution for me.. In the meantime, I tried watching your video but I get this message "We could not locate the item you are trying to view."
  4. You are probably right, I am probably overthinking about it.. While I understand the theory behind this modifications, what I wanted is more of a "magazine reviewer experience".. The so called "in the driver's seat" experience before and after the modifications.. Will I feel the difference on a daily basis when I drive the car ? How much % stronger does it feel in low / mid / high rpm (doesn't have to be exact just the feeling) ? Sometime without the intercooler/chargecooler my car feels like the engine is bogging down, saturated with fuel, not very responsive... Will this change with the addition of the chargecooler and rev faster and feel more responsive ? Thanks !!
  5. Besides the performance dyno data, which is very important, I would be interested to know on a daily drive situation, how the chargecooler makes the car's performance more consistent.. For instance, driving 20 miles, before installation of chargecooler performance would drop off after say 5 miles or in slower speeds, but with the chargecooler, would there be constant high boost power ? Thanks !!
  6. It would be interesting and it would help a lot if Esprit V8 owners could talk about their before / after experience with the follow : 1) Intercooler before / after 2) Chargecooler before / after 3) Methanol Injection kit before / after Feel free to share with us your experience.. Thanks !!
  7. Thanks @mike_sekinger I know this might be too much asking, but any suggestion which water/methanol injection kit to buy for the Esprit V8 ? Anyone have any good experience with a specific system ? Thanks !!
  8. @mike_sekinger Thanks for the excellent explanation !! I now realize the importance of the intercooler / chargecooler... It is not so much the maximum power that is important in the Esprit V8, but the availability of the power all the time.. When things get hot in the intake it appears as if the wastegate opens and releases turbo pressure (my guess) , in combination with what you mention about dumping extra fuel to cool down the intake.. Which drops performance and makes the motor feel kind of sluggish sometimes.. Very annoying.. I also agree 100% with setting goals... For instance my goal would be : -to retain boot space -make the intercooler / chargecooler look like factory -keep the cost at reasonable level -maybe make this a reversible modification just in case I decide to remove this in the future (unlikely, but still no cutting of body parts is preferable) So I have carefully been reading the ProAlloy thread and it seems that the company is having hard time to deliver the kits.. Any suggestions / alternatives ? Thanks !!
  9. While checking this amazing threat about the prospect of Intercooler / Chargecooler on the V8 Esprit engine, I wanted to share some thoughts with you... First of all, from my experience in driving my Esprit I realized that when the car engine is cold, it pulls very strong and smooth.. When it gets hot it appears sometimes like it lacks the punch / kick... Could this be attributed to air intake temperature rising leading to lower boost pressure to prevent engine damage ? Secondly, assuming that a system that cools the intake air is installed, does this mean that the car will sustain turbo pressure more often leading to more constant performance ? And third of all, what are the advantages / disadvantages to Intercooler / Chargecooler ? In my opinion, an Intercooler is a cheaper, simpler setup, provided the air intakes are designed to cool the intercoolers... Furthermore, it might be challenging to avoid long piping resulting in some extra turbo lag... With regards to chargecooling, it is a heavier, more complex and more expensive setup, since it requires water piping, water radiator in the front and water pump.. So the cost is higher and more complexity added.. But it might be the only solution consider the tight Esprit V8 packaging.. Any thoughts on all 3 of the above points ? Thanks !! Makis
  10. I drove my car again for another 30 km of spirited driving with lots of turbo boost and there was no coolant missing.. I am starting to believe that the problem lies in the header tank.. Attached is a photo. When we fabricated a metallic coolant tank , my mechanic asked me if we wanted to retain the sensor and I insisted we do.. If you look closely, there appears to be red coolant on the plastic indicator, so maybe I should do away with this and just plug this opening too..

  12. Update : So today I drove my Esprit V8 around 30 km of combined traffic, highway driving and spirited driving, and guess what, the car performed perfectly and not a single drop of coolant was missing... I am starting to understand what is going on.. When I am driving with a group of more modern sportcars like Porsche 997/991 and want to keep up, or I have a passenger I want to show the capabilities of the Esprit V8, I tend to drive more aggressively pushing the turbos and the engine limits and this sometimes might lead to a little cooling fluid loss... Not sure where it is going.. It could be a) head gaskets b) turbos or c) from the custom header tank which I fabricated and I foolishly installed the stock coolant indicator (My mechanic wanted to make the coolant tank simple with one screw type cap, but I insisted that we also make room for the stock plastic indicator)... So for the time being I will just avoid pushing the car to its limits, and drive it as I always do and enjoy it without any problems..
  13. Sorry, I have been super busy with work... I plan to take the car to my mechanic as soon as I get some time off work and he is available..
  14. I checked the oil and it looks ok... I will go one of these days to my mechanic to check the coolant circuit.. I think he builds pressure to the system with the engine off to see any leak.. John's system looks cool and I also plan to use it to determine what is going on.. I will keep you posted..
  15. I will definitely check to see where the coolant is going.. In the meantime, how do you explain the fact that I can go for 3 weeks without any coolant leak (checking the tank each week) under normal driving conditions... And if I push the car and drive it hard it could lose coolant.. Is the coolant loss related to fast driving (when the engine is under load or the turbos are forcing pressure) so that coolant is lost when the car had been driven fast ?
