Header Questions & Recommendations

Was there a constant dip in power every dyno pull? I can only speculate because I wasnt there to see exactly what its doing, nor datalogging watching the parameters, but it almost looks like the ecu could be pulling back timing....

I dont think its caused from the fabspeed headers, as the graph I posted has agency power headers on the car, which are the same as the fabspeed.

Also to add, its quite common, and especially on many different engine configurations, we have to manipulate the cam angle and/or resonance flaps cross over to maximize area under the curve.

 

I did dyno a while back with and without headers, with exhaust valve open and close. Here is the thread http://www.ferrarichat.com/forum/360-430-sponsored-yellow-compass-group/530482-dyno-comparison-stock-header-aftermarket.html

I had the same dip with Gh21631. The ones with the dip are with header. The two runs are with exhaust valve open and close. The one without dip is factory header, and the two runs are with exhaust valve open and close.

would love to see Fabspeeds response

 

all of fabspeeds published dynos include cats and a tune (along w/ cat-back) and don't have the dip.

I'd be very curious to hear Mase's comments on what he's seen tuning F430s w/ exhaust.

I'm not familiar with OE tuning and their dyno, but it looks like this other stock exhaust car had the 'dip' too:

Hi, I'm contemplating topspeed headers to go with my existing stock cats and capristo racing exhaust... I'm interested in whether you had any heat issues with the headers - did you use blankets or get them coated?

 

I always just went with the carpristo switch in all my cars - sounds great and can close if it gets irritating - of course no hp gain but I don't need a few extra

 

ha thats awesome.
my car is a spider so im hesitant to doing the mufflers since it might be too loud

 

I would like to see that as well!

 

Mine is a spider as well and it sounds awesome, it is like a completely different car now. Next week I am going back to the shop to retune and dyno, I expect the results to be different/better. I'll post results.

 

I'm not sure, I don't have all of the results but we are doing this again to dial out the dip and see if the car has adjusted as some have suggested. This is all good info for the community. So many have opinions but no real data, I will do my part and post the results.

 

Just curious why you believe this to be true. The cost difference to me is inconsequential, I couldn't confirm at any level that one is better than the other. Please provide any facts that you know to substantiate this, I am eager to hear as I couldn't find anything but opinions when researching. 4-1 vs 4-2-1 is all opinion as well, I would love to see some real data from someone other than the mnfr. I will pull the Fabspeeds off and replace in a minute.

 

you have capristo headers, cap hi flow cats and cap mufflers?

 

Fabspeed headers, stock cats and SLine. If they let me back there I'll take some video of the dyno runs and provide sound clips.

 

oh god that thing must scream! can't believe u have that on a spider. ur my hero

 

It really does but I like it, certainly not for everyone and the video clips don't do it justice.

 

No blankets and no heat issues. I don't spend much time in traffic with it though.. I didn't have hen coated either.. Reading everything on the chat I was paranoid about the same and thought I had made a big mistake by not getting blankets or getting them coated but I now have over 1700 miles on them and no issues.

They are a good product, great price.. I took a chance ordering them but it worked out

 

Pretty much my experience as well, lots of opinions but no facts. From a visual perspective the quality of the finish between both are marginal, the performance is all hearsay unless someone proves otherwise. No doubt Capristo is a very good top tier product though, I wouldn't disagree at all. It makes it tough as the consumer, at some point you go with your gut. It would nice to see a 3rd party who is unbiased provide the data that I am for comparison. I am going back to the shop (IAP) to retune and run again to see if we can take the dip out. Unless something changes I will have this info next week.

 

Some tweaking, huge difference. Apparently the car was running too rich which and an example of why you need to make adjustments.

Much better graph and the gains are respectable. The afr readings seem a bit fat until 6200. Did you tweek the a/f on the tune itself?
Glad you got it sorted out and shared with the community.

 

The gains now are certainly more in line with my expectations. Yes, they did have to tweak the a/f which apparently made a big difference. You can feel the additional power, it is very fast. You will spin in 3rd on cold asphalt. It would great to make some runs against a stock 430 for comparison.

 

Was the teeek by way of a new flash file? I'm assuming the file is a generic 'off the shelf' tune. This may prove that a tune is necessary to correct the ecu issue with the absence of the cats.
Did you reset the ecu the first time the headers were installed?

 

You are talking about Stef. He did a lot of work with Capristo and testing for his own car. This is the same guy who makes the great quality LED light systems for 430/360 (scud ing).

You can find all his dyno stuff etc on FLife after it was removed from FChat - it makes for a great read.
