Intake temp too high?

[llenrub]

Cant get power on my rev 2 after engine build include HKS cams. Intake temps rising too high!

Have aquamist water injection, greddy intercooler, 550 injectors on Wolfkatz rail with Aeromotive FPR.

Should be making 1.5 bar, cant get above 1.1 whats going on?

What turbo and EMS are you running?

[raptor95GTS]

what intake temps are you getting?

[llenrub]

Same turbo as Mark Edwards- Turbo Technics Stage 1, ECU is DTA (standalone). Intake temp rising to 70 degrees

[^Trickster^]

Thats pretty high, I was getting about 30-35c at the strip climbing to 40c in traffic.

I was running a greddy intercooler too. But not on a ct hybrid. Is this while driving at a good speed?

Who mapped your DTA??

[llenrub]

This was running on a rolling road at performance turbo systems in luton it was during July and ambient temps in the shop were around 27 degrees but even so, this is still very high and we never got passed 1.1 bar. They've been waiting for cooler period before running again which should be this week, but Im not convinced it will get anywhere near 1.4 bar !

This was all discovered whilst doing final map setup. They've been mapping DTA ECU's for years. I cant beleive that they would be that bad at it.

Probably just heatsoaked to death, did they have any decent fans in there? was it an exnclosed bay for tuning?

Sounds like the air filter is sucking hot air from under the engine lid and the fan isnt strong enough on the IC.

Useing big fans with the bay doors wide open. See how it goes this week with lower ambient temps.

You need a good fan attached to the intercooler - the fans in the workshop wont really help

[llenrub]

3x 4 ft fans blowing air in to the air inlet ducts and the other directly in to the radiator plus the intercooler fan operation- I recon- should have done the job!.

[tonigmr2]

On a warm day all you're doing is blowing warm air about though tbh. Ever thought about a chargecooler?

[llenrub]

Yes..... but I would have thought the greddy would have been good for 1.4 bar and...... I am resistant to spending more money right now.

[tonigmr2]

It is probably good for 1.4 bar on a cooler day! Your intake temps will limit it if it's static on a very warm one...blowing hot air about inside a garage won't help.

Mark gets his power in conjunction with a CC, 'tis the way to go really. Or wait for cooler days.

[llenrub]

Yes it is, but for now I'll have to make the best of it. Perhaps lagging the pipwework and moving the air filter much closer to the inlet duct might help.

[Rory]

Are you saying that your turbo wont boost over 1.1bar or that it will boost over that but you dont because your intake temps are too high? What power are you making at 1.1bar at the wheels?

Rory

[The Morris]

hes got greddy intercooler and water injection. Doesnt matter how hot the day you should be able to boost over 1.1bar

[llenrub]

Turbo working fine. Intake temps were too high. Got a better result today. Lagging pipe, and water spray on intercooler to be re-connected before doing another run.

Is there some sort of scoop ( other than toms scoop) that could be fitted to the external side of the duct to bring more air to the intercooler?

[llenrub]

Strange thing about this is that before the engine build and the upgrade fuel system, it was making much more power. Now its not, I can't see how the engine build is affecting this.

Completely puzzled!
