Weird thing though... I didn't change much.

I knew I was having crankcase ventilation problems previously, but my baseline this time was around 430whp! The only thing I changed was adding a catch can and the tuner played with the timing slightly... So basically same dyno, same boost level and I "gained" ~80whp? Just from a catch can? That is pretty insane... seems unreasonable... but the guy showed me all the calibration numbers and they are all the same as the 355whp pulls. Temperature obviously wasn't much cooler either... Is that believable to you, Geo/Jay?

The ~450whp sheet that I posted was after adding in only like ~1-2psi... Anything more than that and I started blowing couplers off... Trying to decide if I should even bother with higher boost now that I have the power I think I need... If so though, its time for some better clamps and then I'll try again for 22-23psi and we'll see what she puts down. Guessing around 460-480whp.

I might just hit the track with 450whp (and drag radials) and see what she can do.

 

You need some T bolt clamps.

310whp @ 5340rpm sounds is torquey!

what boost? F22C? any ecu logs?

 

Nice build! Too many people worry about BS numbers and like bench racing their cars w/ big dyno numbers. While equal length and fancy manifolds are nice, many people have problems with them cracking/etc, and this has to be one of the best bang for the buck builds. Congrats!

 

You're probably used to seeing unrealistic dyno numbers. His car is pretty spot on for the power level.

Congrats on getting it to the track

 

Most of them are, but some are smaller than others and I was unable to find some of the small ones locally last time I was upgrading them, so I'll have to order them online and replace the ones that aren't.

Yes, the powerband is very nice. I think the turbo was fully spooled around 4600-4700 RPMs if I remember correctly.

I think this was around 19psi. Yes, F22c. Don't have any logs on hand... but what info are you looking for?

Thanks. You are definitely right.

Jay, any thoughts on my above explanation about how a catch can seemingly allowed me to pick up 80whp on the same boost level?

That quarter mile time is from late last year. I'll be there again soon though shooting for 10s.

 

That definitely sounds odd, you did say he added some more timing though right? I have a hard time believing a catch can netted significant HP..? You change your spark plugs recently or any other maintenance? Perhaps the rings are sealing better and the added timing is what netted the gains? Could be many small things that made the difference..

 

If the ends of your piping are not rolled, try welding a bead all the way around about a 1/4in from the edge. That along with some T-Bolt clamps should prevent the piping from blowing off anymore.

Curious to see if you'd gain some power with only a tubular manifold swap. Great power for such a simple setup. Bet its tons of fun.

 

That's how he was able to trap 121mph.. a mileage more suitable to 400whp-430whp Dynojet and 15-16psi. Maybe the correction factors on the dyno are setup different this time. Anyways great #'s now try it at the track for low 11's high 10's.

 

Thats true, it could be many small changes, but not much else was done. He did add in a little timing, but it wasn't much at all...

I did change the spark plugs, but the old ones looked fine.


Yeah, I'd be curious how much I would gain from a tubular swap as well. Full Race advertises some pretty good gains from swapping in just their manifold... but everyone knows how manufacturers claims are sometimes...

My 1/4 mile run was made on the EXACT same tune I dyno'd on. The two events were pretty close together as well. No catch can, no new spark plugs, no added timing was done before the 1/4 mile run... literally exactly the same... But yes, I would not be surprised if 355whp on the Mustang dyno I use would be closer to 400whp on a DynoJet.

The correction factors were not different. I asked the dyno operator to show them to me. They were all the same as the last time. He told me he hadn't changed anything. Honestly he really has no reason to... he has no affiliation with the tuner either, so its not like he has a hidden agenda.

Thanks. Definitely shooting for low 11s or high 10s.

 

My Guess. High 10's/ low 11's at 125.+. I trapped 121 on a shitty launch and 450whp lol.
