It took about 20 minutes but then I hit a minor problem, the hose was
now too short as the new actuator is base mounted. Jumped in the car
at 6:00PM to a local lotus specialist and nicked some hose and two
clips off them.
Now the car runs like a dream. Boost is about 0.9BAR. Iam going to
turn it down but I think the lowest is 0.85BAr (12PSI). Before when I
tried to turn the boost uo, it felt jumpy. Now it's smooth nad wow
the power. I will check it into *** Emgineering next week to check
the fuel mixture to make sure it's not running too lean.
The engine is OK at 0.85BAR as at had been overboosting at 1BAR for
three and a half years.
If anyone wants to buy one for their carbed turbo, then please drop
me an e-mail and I will try to work out a price. I may stock them if
the interest is high.
Next will be the BOV, which I have already purchased and is fully
adjustable. Let you know how I get on.
I will be working closely with another fellow member on other carbed
turbo mods that are affordable. keep you posted.


Cheers,

[quote=th4neuk]Dave,

That sounds great. So this is a smooth and easy way of upping the boost on a carb/turbo car. I am definately interested. Let me know about pricing etc. I might know a couple of people who also might be interested in this mod. There doesn't seem to be much out there for the carb cars without going to physical engine mods. With no ECU chip replacement is impossible.

Cheers Alan,

I reckon that I've found a supplier with a lower rated spring actuator that's cheaper than the one I bought. Iam going to see if they can do the same specification. If they can then the only other issue is seeing if my spring fits the other actuator to give people the option of starting off at a much higher boost.
If this works, I reckon prices would be around £70-80 mark. If not then it looking like more.
I'll also find out what PSI range is the other stock one. I know mine has a range between 12 and 20PSI which is more than enough. I have it set almost to the minimum, so Iam thinking of using the other ones with a lower spring, just turned up a bit.
Let me know how many you want.

cheers,

Jim,

I've been liaising with my local Lotus specialist on some of the responses, especially a thread I did a while back on improving the performance of a carbed turbo. My mechanic tells me that my engine even though it's a carbed turbo is different to yours. Apparently there were many engine enhancments done in 87.
I printed off some of your replies and my Local Lotus guy said that you certainly know what you are talking about and that everthing appeared to be exact and precise but it only applied to your type of car.
Iam really confused now, my head's cabbaged.
Iam not in any way trying to undermine you or question your expertise. I know that you really know your stuff.
I will drill my Lotus Specialist again to find out whether my engine is really any different to yours. If it turns out that this guy in wrong then I appologise to you in advance.

Many thanks again for your help and assistance, keep in touch.


Cheers,


Dave Walters

P.S.,

You can also add a water injection system to aid in reducing the charge temp, but these can be cumbersome and have marginal results. Happy Motoring! Jim'85TE


Thanks Jim for the info, I'll print it off for future reference.

cheers,
