Title: any point it stage 2+?
Post by: chris s on December 29, 2011, 08:19:48 pm
Can anyone let me know if there is any point in moving to 2+ without an intercooler? My ed30 is running stage2 with a BCS TBE and ITG and I've just bought an autotech HPFP so will get that installed anyway. Thoughts much appreciated guys

Sunglasses_Ron ran his on just the standard IC and his RR graph looked like this.

you can do temporarily but long term you should upgrade IC or stick at stg 2 really - ask revo

Stg2+ on stock intercooler is fine, however intake temps can get around 15-20 degrees higher after a few 3rd and 4th gear pulls on the road. Dyno shows that a K04 car with cooler can make 10-15hp more as the cooler temps allow a few more degrees of timing advance.

from the countless stg2+ cars I have mapped I would say 90% had stock coolers.

Perhaps the bhp reading on a dyno could not be accurate for a car with the standard intercooler. Its not really getting up to temperatures that it will out on the road as it is just for a short burst.

Depends on the fans the dyno is using tbh.

What's stage 2+ BHP then with THS and autotech internals, BCS system with 100cel cat, RS4 valve, and a ITG?
I'm curious? Thought they get about 350/360BHP but if the one above is getting 355 with standard IC what would my ED30 get then with Revo?  :popcornsoda:

As mentioned already, IC is not essential with Stage 2+, especially during the winter. However, during the summer months after a few WOT runs, my car would run noticeably slower and if I were to go down the route again I would opt for a Twintercooler or similar (just wasn't worth while for me, as the car was going soon after).
On a 1/4 mile run for example, if 2 x Stage 2+ identical cars were to run against each other and one had uprated FMIC compared to the other having OEM. I would say there would be bog all difference (mine was certainly quick enough for minimal mods :surprised:). If both cars were on a track day though and were continuously being ragged round the track. The OEM cooler'd car would soon be struggling after a couple of laps.

Depends what your circumstances are really and how long you intend on keeping the car. Even with a oem cooler'd car, it will be a seriously quick hatchback!!!!  :driver:

This is better scaled plot of the same RR run. This was before I changed the Dbilas intake for a EVOMS.. (which was noticeably better IMO, just never got it on the rollers again to see  :sad1:).

In the winter it makes next to no difference IMO. I logged mine in 5/6oC AT and even when knocking the timing upto 8, I got next to no timing pull on continuous 3rd and 4th gear WOT runs..  :surprised:
