    ZL1 interchiller 1/4 mile results

    Robert has had his interchiller fitted for a couple of months now and recently took it out to Cecil Dragway to finish off the racing season. Not only is the 60ft very impressive being he is still on a 20" wheel but the consistency of the interchiller is highly evident 10.078 and then backing it up with a 10.062 @ 137.67mph and look at that back half track mph gain he is picking up over 30mph from not pulling out as much ignition timing due to the colder intake temps of the interchiller.

    This car was tuned by Jeremy Formato of Fasterproms and here is what Jeremy had to say after tuning Roberts car.

    Looking for colder IAT's? we have achieved 11c IAT2 on a 41c day and -8c during winter.
    We have proven cabin AC vent temps are better than GM spec, both IAT2's and vent temps are all on video with nothing to hide.

    I had my VF GTS tuned at GM Motorsport in Melbourne with the 550kw package, if I fitted the inter chiller and the reserve tank and cooling plates do I have to get it tuned again ? Or does the tune in the car now advance the ignition due to the colder air or does it just not reduce ignition advance due to little heat build up ? Means a trip back to Melbourne from Adelaide if so ?

    If they have done a good job and tuned the intake air temp table to suit various temperatures then you wont need to get re-tuned.

    Is it auto or manual?
    Manuals are known for trapping hard in the last half of the track having a high mph with an ET that doesn't usually match that of an auto.

    An example of this is I have seen plenty of guys trap 135/136mph in an auto and run 10.2-10.3 where as the manual guy trapping the same 135/136mph is usually around 10.6-10.7

    The manuals usually come home very hard but are slower on the first half of the track until they can stretch their legs in 3rd and 4th gear.

    In terms of interchiller consistency this post about the current fastest 6.2L LSA GTS sums it all up in my opinion any other PD blower car yours included wouldn't have that consistency in that short time frame without some serious cooling aids or you are consistently running the same "hot" temps and it's giving you consistently the same results from being hot, as you should know in your blown car the 1st run of the night depending on the air temp is usually the fastest as the more you race the hotter that blower and engine get:

    @ 9:20pm he runs 10.177

    It takes roughly 5min to drive back following the return road speed limits, collect your ticker and line back up so in roughly 15-20min he has done a 2nd back to back pass any other car would be losing HP due to heat soak.

    Yes mine is manual but im not pointing out the end trap speed but the fact it could still pull 30+ mph with no break in between. At 1:56pm i ran 216.81kmhr and at 2:12pm ran 217.53 engine might of been shut down for max 5 min which would of only given more heat soak to the blower

    your 60ft
    1/8th mph
    1/4 mph and ET

    On both of those runs?

    Nice work

    proves what I was saying though about the manual/auto ET/MPH

    An auto traps 10.2-10.3 at 135mph and you trap 10.6-10.7 at the same mph.
    As said the manuals always have more legs on the back end.

    What would be interesting is to control the intake temps with a chiller or even an ice box, tune the IAT table to suit and then see what improvements you see.

    But yes the manuals always trap hard mph with a slower ET.
