BSR Tune: Nock?

[Tantram]

I was looking at the BSR Tune and am extremely interested in it. My concern however is can our stock intakes/exhausts handle the increase of boost? In my experience with anything that increases boost it was always required to increase the flow as to avoid nock.

Do you forsee this is a problem? Would you upgrade the flow components at the same time to avoid this?

Welcome to the forum!!! Good question. Anyone have thoughts here?

Wrong question!

Right Question: can the turbo handle the increase of boost?

This tune was made for a stock car with stock components, im sure bsr will release a tune later down the road for an intake/exhaust but for now its for a stock car.

At first I was interested, but am now skeptical that the stock turbo will live a long and happy life at 23 PSI. I'm much more interested in upgrading the intercooler.

European tuners talking about a maximum of 10 Hp (and not 25 WHP) on a stock rl.

They say thats 25 WHP are impossible.

I tested a Opel GT on a dyno and we had only 68° F air intake temp
(outside temp. 54° F)

So what the hell should the big ic do here?

Above 140° F air intake temp things may change...

I often drive whe the ambient temps are 80 degrees and above. A larger intercooler will definitely be an advantage.

80 are nothing....

...you can have over 100 degress ambient temperatur.

Still your intake temp is below 140 degrees everything is fine and a larger ic cannot work.

I don't know about that...I have the Dejon intercooler and there is definitely an increase in power you can feel it. I like to use a on-ramp (highway) to see my improvements. I use to go 0-80ish before the add ons and now it is easy to hit over 90 with the to new exhaust and intercooler.

I'm sure that German GT will be along any minute to tell you that you are wrong....

You know that your IAT sensor that you are reading is before the turbo right?
We logged 230F inlet temperatures going INTO the intercooler. There is NO way to test an intercooler correctly without putting your own sensors in the two couplers going in and out of the intercooler. Those of you who have HPT, Dashawk or some other data logger that plugs into the OBD2 port can NOT log actual temps coming out of the intercooler.
You guys cant get 25whp out of a stock opel gt? Wow. I'ver seen it happen several times with just our intercooler and exhaust.

I agree with the combination ic and exhaust:
maybe 6 to 8 hp from the ic and the rest from the exhaust.

But unfortunately the exhaust is illegal in europe
(and i think in most states of the us too)

Actually, we got 25whp from the intercooler.

HPT can read the iat2 sensor thats on the cold side pipe, the dashhawk will in the future.

Our stock intercooler is actually pretty efficient for an oem intercooler, i logged the iat2's and they were 30degrees F above ambient. Not sure where how its possible to get 25rwhp with an ic upgrade, even if the ic was 100% efficient that 30F temp drop would not net you 25rwhp. Either the stock ic is highly restrictive or theres a huge pressure drop or something else is at play.

We have both Dashawk and HPT. The readings were different than the readings we got from installing an actual iat sensor on the couplers before and after the intercooler. Your stock IC is going to work well until you start driving it HARD. The 25whp is from both flow and efficiency. We have seen 50-60whp drops when intercoolers get heat soaked. The gains are more power loss prevention than anything. All our gains were recorded with atleast 3-4 runs on the dyno.

Well the ecm uses the iat2 sensor to read the intake temps, it cant be that inaccurate. Maybe because you installed it at the coupler and not where the original iat2 sensor is?
But no doubt about the heatsoak problem, after an autocross lap the outlet ic pipe was a bit too warm to the touch on my car.

"a bit too warm" to me translates into 140 degrees or warmer...wow

Exactly what i'm writing

As long as the temperatures are in the green range everything is fine with the stock ic and you have no gains from an upgrade.

Thats exactly my opinion. Heat allways means power loss.
And on the dynos you use - you are very fast in the overheatet range.
So it's clear that you can see a gain of 25 whp with a larger ic.
