RC Flint was nice enough to send some datalogs to us from his super badass 6 second LSx powered s2000. Many of you probably know this car. It’s fast! And has completed several drag & drive events over the last several years. The car has been through a few evolutions through it’s time, all the while running several different versions of our intercoolers…. 1800hp Hi-Ram coolers, 2500hp TSP Liquid-air, and most recently our 3000hp TT liquid cooler.
This post is going to focus on the 2500hp liquid-air intercooler mounted to a Texas Speed Titan intake manifold. Here is a quick rundown of his engine combination…
- 414″ LS3 Headed Engine.
- Shearer Fab 2500hp Texas Speed Titan Intercooler.
- 114mm FIS Turbocharger.
- Davies Craig EWP150 Pump w/ 7gal Ice Tank.
- Fueltech EMS.
Onto the data! Here’s the breakdown from the ET on this particular pass..
60′: 1.188
1/8: 4.570@161.63
1/4: 6.981@203.74
390″ LS, 114mm Turbo at ~48psi of boost pressure.
- The intercooler is effectively removing 340deg of heat from the intake charge at 230lb/hr(2300hp) worth of airflow.
- Pre-Intercooler temperatures max out the sensor @450deg. Likely touching a peak of 460-465deg.
- IAT starts at 93.2deg and finishes at 130.6deg. That’s a 37.4deg temperature rise in a quarter mile pass @48psi of boost.
- Look at the EGT’s and how closely matched all 8 cylinders are. A benefit of running intake mounted intercoolers. They improve intake manifold distribution dramatically.
Two things worth noting…
- There was not much ice in the water tank and the IC was not prechilled.
- Even better performance can be expected with better water pumps. Such as the Davies Craig EWP180 or Mezeire Billet Intercooler Pump.
Here’s a quick video touching on all of the data points throughout the entire pass..
