Nice number!!30whp is a good gain!!This car is using HFC,so i think the TB part will replace the TP.

 

Not sure if I can provide any usefull info. If I remember correctly, DB tested trottle bodies to give 5-10HP when the intake manifold was port matched to the bigger throttle body.

This might have a slight effect on before after numbers, but so would anything else like decat, LICP, intake..... I doubt that it has as much effect as the before and after tunes though! It is gonna be almost impossible to determine an exact number for HP gains with a given set of cams as people have different mods / tuners / gas / temperature.

IMHO, Works graphs show that there is SIGNIFICANT gains with cosworth cams.

 

The power increase and torque increase should be the same percentage for any given RPM by definition. Why aren't they on your graph?

Was your run-to-run variation THAT high?

 

These are very nice gains but they also are due to the high lift of the cams which gives even more power.. Im assuming these are more aggresive than the 280s..I wana see some results with other members here that have bolt ons and stock throthle body

 

The WORKS Aperture Throttle Body is already matched to the inlet on the stock manifold. There's no need to port anything. (The WRP Aperture II is larger than the OEM inlet could be ported to match for more airflow.) As stated previously, both before and after runs were done with the Aperture on the car. In general, we see 8-12 HP gains with the Aperture, but most of the difference is in throttle response. Again, we were trying to provide a good comparison for the cams alone while at the same time getting results for the WORKS TR-340 package for the IX.

 

Jamie,

Is the trottle body of european/japanese/american IXs the same and would I need a custom tune if I just install the works TB on an otherwise custom tuned car with my mods + cosworth cams?

TIA, Can

 

What do you recommend safely revving to with upgraded internals then? The dynochart cuts off at 7500rpms.


Oh, and thx for hitting a good candidate! Exhaust/intake/tuned --> perfect choice!

 

When a product is introduced into this market we want to see(or maybe it's just me) what that one particular product makes not what it makes with other parts as well? Regardless if a person would put cams in a stock car or not. I think something has been lost in translation here.

In order to provide honest & valid numbers as to how much a single product makes, one must dyno a stock car and then dyno that same car on that same day with the new cams installed. The difference in whp and wtq is the real world data of how much the cams make. Seems pretty simple to me. I don't understand how you can justify your statements and these results by saying: "Well it would be useless to install cams, if you didn't do all of those other mods first." That's not what is in question here, What is in question is: How much do just these cams actually make. And these graphs prove nothing to that effect. They prove how much they make with a Works TR-340 package installed. 2 totally different results.

 

Yeah after reading a tad, these works plots do seem a bit fishy (seems as if the pulls were done on different days, the graphs dont quite line up correctly)

However for your enjoyment, GSC just posted plots, before and after on an untuned car, then tuned it (kinda)

Then you will see where im coming from. Ill stick by my statements however, cams on a stock car-huge waste of money, cams un-tuned-huge waste of money.

Spending $600+300-400 on cams on either a stock car or an untuned car is really silly. Like I said, you only start to NEED cams once the flow through the head starts to outpace the duration that the stock cams provivd, on a 100% stock car, cams wont be nearly as beneficial.

Before and after plots of un-tuned cams doesnt tell you anything either, in fact as you will see with the GSC cams, the car lost power in some areas due to the car running rich, I dont see why anyone would base any sort of decisions to buy or not to buy on such a comparison

Where cams really shine is when boost levels are elevated and the car is properly tuned, as that is where you will see the largest deltas. This usually happens with a full TBE/filter/raised boost/tune. From the modding stand point, cams are usually the next logical step, so to compare a TBE/filter/raised boost/tuned car vs the same car with cams is the best way to go (IMO).

Unfortunately GSCs car was not tuned at all before the cam install, so its hard to say if the delta in HP was due to them leaning out the AF or mostly due to the cams themselves

 

We set the rev limit at 8K with the WORKS Brain Flash when using the upgraded springs/retainers on the stock short block. If building the bottom end as well, we can go higher.

 

Was it a Mustang Dyno that you guys ran on? I just dont see how you guys had all these parts on the car and only made 313whp with cams.....I know on the Dynojets IXs make over 320 with just TBE, Intake, and a Flash (with boost turned up). Does your flash turn up the boost as well?

 

We aren't concerned with the peak number. The number of interest is the difference before and after as that was the sole reason we did the "baseline" runs. It could have put down 100 before & 110 after or 500 before & 550 after. The results would have been the "same" as far as the gains from the cams are concerned.

The WORKS Brain Flash P2 keeps the boost from tapering through software changes in conjunction with the WORKS Boost Hose assembly. We typically target ~20 PSI all the way to the rev limiter on pump gas, but can increase the target PSI as well as taper up, taper down or have it follow a sine wave.

 

Ok, so your baseline run was a car with your TR package, right? I guess making 31 whp and 29wtq is pretty good for just adding in cams (if i am getting this correctly). Whats the average whp and wtq for a stock IX on a Mustang dyno?

 

The mods are listed for the base run (basically a TR-303 with the addition of our filter, DP and HFC). The cams made it a WORKS TR-340 (plus HFC) gaining approximately 11%HP/9%TQ on 91 octane.
