Does someone know what will be a reasonable power package choice with an upgraded air/air intercooler (Forge/RLS,Lotus)?
260HP Max? If we see the latest Lotus versions?
I think this info is required when you think of the upgrade traject that you want to take as today we have apparently 2 options:
intercooler air/water and go over the 270-280HP (Sinclaire/Komo-tec)
intercooler air/air (bigger) and ??
I would say its very difficult to say tbh, also its very difficult to give a fair comparison of an air to air vs air to water because a dyno is the worst possible enviroment for an air to air cooler.
What you really need is to take inlet and outlet temps on the move to see how the Forge would compare against a chargecooler for example.
I am not totally convinced by the 20bhp gain of a chargecooler over stock as I cant see how it makes the car run any better than optimum for more of the time? When I was driving my car the other night in -1 deg ambient conditions am I pushing 240bhp?
There is no doubt that the chargecooler is a cracking set up and it will give great dyno results as it will take much longer to heat soak on a dyno than an air to air, but it does cost alot, there is alot involved in install and it weighs alot more. Will it perform better than an air to air? no doubt. How much better? good question.
As for guessing at figures if Lotus produce and warranty a car running 255bhp wth air to air I would guess you could get 280 without a problem.

sits back and waits for Dad to mention trackdays
Edit<< just seen Franks post so not a bad guess at 280
Also to add my question about chargecooler adding 20bhp is a question, on re read it looks like I am saying it cant when I actually have no idea, I just dont understand how it does.
The thing to remember is without a proper tune to take advantage of the cooler air charge you only maintain not gain HP …
Thats my point really, they just seem to quote a 20bhp gain for a stock car with a chargecooler fitted? but as you say the way I see it is that you’ll just keep optimum bhp for longer with a chargecooler on a stock car.
RSL is a waste of money and shows no improvment over the stock S…
Tha last S we tuned had the RSL…numbers don’t lie…save your money up for a proper chargecooler…

Hi Frank, sorry but do you have an official company? (linked to Sector/Gotham, etc?) Just try to put a name on you
So for you the chargecooler from Sinclaire or Elise-shop is the best besides the Gotham remap?.. it looks like a one-one match
I have to say that I don’t race my car… so we speak here about adding extra HP and keep everything reliable for a “normal” usage
I’m ronin the guy everyone hates just a bit less then Scuffie…
I came up with the ronin/katana kit that Sector111 and Sinclaires sell… I worked with Charlie to come up with the ronin/Gotham tunes…
My old setup was 320 rwhp SC and my curent setop is 459 rwhp turbo…
I don’t race my car either but I do hammer it from time to time in the canyons here in Cali.
Charlie and I did all the tuning R$D
I sell nothing this way I can always tell it as I see it…check out www.monkeytuner.com and any of the canyon run videos on U-Tube, look for videos by svronin…
Dude it’s a Lotus nothing is reliable…it’s an adventure…
Couldn’t someone organise a propper independant back to back test between the intercooler upgrade and the charge cooler?
It would be interesting to see how the two stack up out on the open road, the chargecooler will no doubt always be the winner on the cooling front but it would be interesting to see how well the two performed out on the road in practice.
In fairness though the answer will depend on the application, if someones looking to keep weight down and not looking for more than 280 bhp then the intercooler is a much cheaper and less complex install. If they want big numbers then I would think that charge cooling is the only way.
Comparison of “on the road figures/times/performance” at this level, is a load of bollox in the real world. Even a 1 sec difference in the 0-60mph, or 0-100mph times is totally meaningless, except for bragging in the pub. Anyone razzing on the road anywhere near to the Exige oem limits, deserves all they’ll get if caught by the boys in blue.
Far, far better to get the suspension/geo, then the brakes set up properly, & also learn to use the car on track as you go along, before wasting money attempting to increase the power, otherwise you’ll be made to look rarher silly on track. And yes, I am speaking from my own experience over 8 years, so I’ve been there, & learned the lesson from the expensive/hard way on over 70 trackdays.

Do you have that post stored in your PC ready to copy and paste?
You will need a remap to get any better power from an upgraded intercooler. I would have thought that just fitting the cooler will not inrease the power. The cooler will provide lower temps so the person remapping can change the spark timing to get more power (I think advance it?).
The cooler will be prone to heat soak, like on the subaru. But if you look at the latest 400bhp subaru tunes that are available from the likes of Litchfield ie type 25, they run the standard top mount intercooler which they say is good for 400bhp. It may be worth looking to see what kind of design these are, whether tube and fin etc. Then just need to get enough airflow through it. The roof scoop always looked small to me, but then Im not a car designer!
