Unhappy loss of power

today was the first day i had a chance to test the car since i fitted the code3 pulley,intake and ph spacers..due to delays of sparkplugs arriving from let,i have not touched the sparkplugs..the car is running fine on tickover and fine when driven normally
on the way back home,i was doing a steady 70mph when i noticed a porsche 911 turbo,audi s3 and a subaru coming up fast,so i unleashed the devil..for some reason there was a loss of power before i hit 100mph
i know some people are gonna say the sparkplug gapping but i cannot see why it will happen at this speed..
what do you think the problems will be??

I see from your list of things ordered that you are awaiting the CM30 pump

hopefully this will arrive soon as it sounds very much like you have the dreaded I/C pump failure.

good luck

LET C32 2002
I would expect the loss to start alot lower then 100mph but maybe it could be a sign the OEM pump is starting to fail. Please keep us updated to what you find is the cause.

You're running increased boost without the corresponding increases in your cooling system (i.e. larger HE + Johnson pump) - consequently, I agree with others... you're likely experiencing a failing OEM IC pump, and/or engine heat soak due to insufficient cooling capabilities of the stock system.

The good news is, it appears from your "WAITING FOR" list that these items will be addressed in short order... which should remedy your situation quicker than you can say "Bob's your uncle."

Is there anyone else experiencing this problem???? Is it a common issue if you only have Code3 pulley and intake (without IC and some other stuff)?

The reason I am asking is because I ordered Code3 pulley and intake and planning on LET ECU tune (but not soon), but have not been thinking about some other stuff (short on money).

I was wondering the same thing...but I know other members running just a pulley no tune or cooling upgrades and they seem fine thus far. I hope we find out eventually the cause.

I had a bit of troubles and wait and communication problems with Erick @ LET when I bought my IC PUMP and HE. In the end he came through and gave me a good deal so I was a happy customer and he was a satisfied vendor I hope. It was like a 3 week wait. I don't see why it's 3 weeks. I constantly hear people saying they are waiting like a month on some parts and its common here but when I ordered parts for my 300zx.....I had a tracking number like 3 days later. I guess there isn't enough tuners/suppliers for Benz. Bottom line is give it some wait pretty much everyone here had a good experience with LET and Code3 I believe so that's life.

i agree its probably the intercooler pump.

As for why you have to wait three weeks. My theory is that they probably go by a just in time inventory buying cycle, like most retailers do. They probably buy enough inventory from there manufacturer for a month, so if there out of stock and you put in a order. Your order probably won't be filled till the next month when they buy there next batch.

This keeps inventory low and over head low as well.

Its a technique made famous by a lot of the major Japanese companies and Michael Dell.

The bank usually floors for about a month, more then they have to paid it out in cash, so most companies only try to keep a months worth of inventory.

ECU issues. Talk to your tuner.

It could be but don't leave the I/C pump out either. If your(H13BS M) tuner is local cool but if not I say replace your I/C pump just to be sure...the CM30 Johnson pump works great as a replacement and much cheaper then stock but if you have warranty then have then replace it first(H13BS M)
