I think there was only one person on here that had problems with too big of an intercooler, Nicklatech. Might try to find his thread about it... otherwise go big...

Any of you guys have problems with boost lag on a large intercooler? My engine will be mostly stock except for an hx30 and the pump tuned and I was going to do a 7.3 intercooler.

Boost lag is a characteristic of turbo charged engines, compared to mechanical supercharging or NA engines. Are you new to turbos?

I run a 31x12x3 intercooler on a 2.2l Kubota v2203. Most guys run half the size. If there is any more lag it is minimal and worth the trade off

I’m using the same cooler that was from the bread van . HX 30 , governor spring , pump turned up a touch , fuel pin , smoke screw adjustment , 900 * EGT is all I ever reach on the steepest graders fully loaded . 3.54 gears Nv4500 through a NP205 , truck weights 6900 lb empty . 2500 RPM @ 70 MPH

Is your EGT reading believable? 900F is what I get on a level road at 100km/h with a slight head-wind. Engine producing about 30kw.

Check the probe reaches the centre of the flow. Is it pre-turbo?

I seem to think it’s very close , I checked to exhaust manifold and turbo housing with a laser , damn close to the same thing . Cruising , I’m running around 15 lb boost and 650* . I can’t say if this is good bad or I’m just stupid , it is what it is . When I was running an H1C EGT would hit 12-1300 on the same long uphill grade that I now hit 900 . I did nothing but swap the turbos .
