Hi everyone I'm currently a Porsche guy with a 86 911 and a 2012 Cayman. However, the Lotus bug has bit me and there are a few Elises in my area that are on my list. One has been modded with a Magnuson MP62 supercharger and intercooler. The HP claim is 300+. I hope that claim is inflated as that would seem to me to be pushing the stock NA engine more than I would like. Does anyone have experience with such a setup? Apparently the dealer has had ECU problems, it is not the S flash but a custom one and somehow it "went away" (according to the sales guy). With some effort, the dealer found the supplier and had it reflashed so the car is running. Does this story make sense to you? I thought a flash into memory was a permanent thing. Anyway, I am quite handy and capable of trouble shooting and analyzing systems so these issues have not made me run - yet. One thing for sure, I would want to detune the system to be more in line with say 230 HP. IMHO, that is plenty for such a light car. I haven't seen the car in person, all this info is from the sales guy and pictures. On Monday, I'm going to have a really good look at it and will take pictures of the SC setup etc. I have viewed the Lotus buying videos, many thanks to Rob Dietsch for putting all the effort into them.Any thoughts and/or suggestions welcomed. Thanks!

I am not a fellow that knows supercharger brands, but I can tell you:

I have ~300 hp at crank, i.e. 254 a wheels. You don't say where that 300 hp supposedly is, but the distinction is important.

And....

Note to new Elise & Exige Owners:


1. These cars have large (i.e. dangerous) blind spots. Multivex mirrors are NLA, but RLS (Really Light Stuff) offers very good tape-on replacements.

2. The horns are way too weak (quiet). There’s an inverse relationship: smaller the car, louder the horn needs to be.

Get something such as a Stebel Nautilus.

Stock: “Excuse me”

Stebel: “HONK! LOOK OUT!”

Remove the stock horn; replace with louder.

(I drive with my finger on the horn button in any traffic. Iffy situations, my headlights are on.

Stay to the left of traffic, i.e. avoid passing on the right if you can.

Stop way behind trucks, SUVs, etc. Some have blindspots >50’. )

3. The early cars came with misaimed and dim headlights. If you drive at night, convert to HIDs. While better than stock halogen bulbs are available, HIDs throw more light. Stay around 5000k. As of this writing LEDs are not as good.

4. Ensure your car has had the work required by the recall for oil line fittings done. You could lose an engine and/or spin in your own oil.

5. Transmission:

The best transmission lube I’ve found is Redline MT-90 plus a little Power Punch Extreme Gear Oil Additive. (Note that it takes two changes to get rid of the previous lube.)

a) Early cars have wobbly shift towers. Look up Stan’s Mod (bolt and spacer; http://www.billswebspace.com/ShifterReinforcement.pdf) and

And, use:

Re-Enforcer long thru bolts that terminate under car and tie down the tower:

https://www.inokinetic.com/lotus/re-enforcer?category=Transmission

These (lube, mods) make a huge change in shifting.

6. As per some engine builders on these sites, wait AT LEAST 20 -35 minutes after coolant has reached full operating temp before engaging cam switchover.

For street cars, consider removing one or both oil coolers. Some cover them. Oil doesn’t get hot enough on street, leading to cam wiping.

I use Mobil 1 5W-40 Turbo Diesel oil. 85k miles and fine, but one is not a useful example.

7. Rear toe-links can loosen and break with disastrous results. You can check tq periodically, or use Nordlock washers. Best is conversion to better engineered brace, such as BOE’s InoKinetic’s for two examples.

8. While under the car with panel off, look around for hoses and wires chafing their way to failure. That’s how this was found:


9. The stock radiators are prone to leaking where the end caps meet the metal part. Keep an eye on this. Most of us use single-pass all-aluminum radiators.

10. When your wheel well liner comes loose, skip the lame plastic rivet and use Well-Nuts instead.

11. Life will be better if you disable the auto-arming alarm function on the earlier cars. You won’t have to press a button to start the car. Instructions:

12. These cars cannot be left off a Battery Tender for weeks at a time. Unless dead batteries are a particular joy of yours. Buy one right away. There are numerous threads here about which ppl use and like.

You NEED a digital multimeter (voltmeter) to work on modern cars. Handy around house too. Get one this week.

13, Some on this site are a bit obsessed with hockey pucks for lifting the car. Don’t use these. Too hard and slippery, generally, and too small a surface area. Use a piece of wood, as your hero does.

14. If you are fooling with sparkplugs, remember to slather those tubes in dielectric grease (prevents shorts).

15. Visit the Uber Thread

http://www.lotustalk.com/forums/f3/elise-exige-uberpost-read-everything-you-need-know-here-25131/

16. Most parts on the car are made by Toyota and others, so buying things like a/c compressors, engine parts, etc. is wildly expensive when purchased thru Lotus.

Toyota dealers, auto parts stores are way less expensive.

17. The soft high-grip tires on most of our cars lose much of that grip when temperatures drop below 50 F. I know of too many ppl who spun their cars when not remembering this. I use hi-performance all-seasons.

Note that many summer tires cannot even be stored in temps below 20 F.

Oops. Forgot to mention that BOE (a company I really trust) makes a 400 hp version too. The 300 version is very reliable. Don't worry. There are other S/charger vendors, but I voted with my checkbook (OK, credit card.)

I went with a flash (Blade 300) and supporting mods a few months after purchasing my 2007 Exige S. Stock SC (MP62) with a better intercooler, injectors, flash and smaller pulley. 281rwhp, so about 325 crank. It's been very reliable and I've had no issues in the almost 9 years I've owned the car. I'd like to increase the horsepower, but I'd need a built block, REV400 or REVX and likely a built transmission. That would be nearly $30K, so I'm sticking with what I have. I have a few other toys that can satisfy my desire for stupid acceleration when needed.

Thanks for the wealth of info glb and oldmansan. Lots to digest there and I am encouraged by your statements about the 300 or so HP number not being an issue (as far as longevity) . I'm really looking forward to learning the brand and of course, driving it.

Torque curve, what torque curve? It's almost a wonderful straight line. And HP just builds in a linear fashion. OK, I'm in with those numbers.

I didn't say curve. It's not bad for the stock SC.

No San, that was me making comment and admiring the dyno graph. Thanks for sharing it. But based on the just shy of 300 HP, I thought it was your car, not a stock one. Is that how the Dynojet expresses it?
