Ps I'm selling all my OEM stuff unported so someone here can buy it, send it out for porting and install on their car so it's not down for a week or two.

 

Tuner got a job in California. Before he heads out he's doing some group tuning before hand. The new date looks to be July 7th

 

Update first page

 

Damn nice write up man ! Defiantly looking for the numbers when all said and done .
Still I the fence about doing anything like this , price vs power gain ? Thanx for all this work

 

Well for $199 TB's and $100 for the manifold, after intake and exhaust where else you going to find HP for only $300? Add the upper for $295 and even at only 5 maybe 10 HP it becomes worth it.

 

Just went for a test drive. Surprised it went great. I thought the TB's would need the idle screw adjusted but it drove 100%. Good to know when you need to drive to the tuners.

 

You'll be a 100% right if the gains are there . I've been waiting for someone to dyno a car with only the Z1 or Motordyne manifold ( yours been the same if not better ) , intake and exhaust , seems like I the ones I see are with headers and TPs or HFCs . And I wasn't impressed with the sub 320 WHP . When you can get to that without the Z1 or motordyne mani.

 

I'm a little confused, not 100% sure what you mean. Do you know my mod list? I have more on there then just the intake setup. 320hp also isn't bad as long as you're on pump 93 and SAE correction factor. That's a good 50hp increase from stock. Pretty good for a NA car to pick up.

 

I don't did I miss it? Do you have headers and or HFC's? Intake and catback and what you have done with the port and polish is what I was looking for but looks like you might have more? Sorry man

 

Its cool I just thought you were talking about me only doing the intake porting. Was just letting you know I have a lot more so fingers crossed I do break 320hp on SAE 93.

 

So I finally got tuned today at Smokeys and I believe the 2nd here. Although the old tuner is gone for reasons that aren't good I guess. To my great surprise the car was still rich! It was rich stock I'm sure, rich with a CBE and CAI, rich with a LTH, and rich with ported TB's, ported upper and lower manifold. Average looks to be around 11.6-11.8. That sucks because I was taking it easy for fear of being lean for like 3 weeks after the manifolds and TB were installed.



Now after the tune its running around 12.6-12.7. The tuner said some run into the 13's but we felt safe with it turning into a track car to not make a dyno queen. I was told timing had been picked up around 3-4 degrees and there were some issues with uprev. The data logger was acting up only getting some of the items at times and the 2013 ROM wasn't doing what he wanted it to do. He would tell it to do things and it wouldn't 100%. Pretty much took all day after waiting 2 hours for uprev to email a license and some other things then start to build a new MAF map.

Since the car was rich he did a base run pull with the OEM size MAF housing so we could see a before and after on his dyno. I've never been on this one before and never heard of it. It's called a superflow AWD and uses something called STP instead of SAE or STD. After the base he started turning everything up. We swapped the MAF from 2.5" to 2.75" and finished it up. Results look to be around 15hp and 6tq at max peak with around 15hp and 15tq above 4500rpm in the mid range (minus that base run boost from 6300-7100). Pretty much what I thought a NA tune would do.



Next I have to get back on the dyno I've been to a few times before and really compare all of them!!

Mods.
Customs 2.5" true dual CBE straight pipe
LTH
Custom 2.75" CAI
63mm ported TB
Ported upper mani
Ported lower mani

 

Dyno day.

 

Its late anything?

 

Well if I didn't have bad luck, I'd have no luck. I had a feeling my car was just not the right test car. I think to much has been done and I'm just not sure. I really can't wrap my head around what happened. I'll try to do my best to explain. If you want to chime in I'm all ears!!

Ok I'm just going to compare my last dyno to this dyno with changes, the floors yours after. PS, I will find a local 370, take his car there, dyno, add parts, dyno. It's really the only way!

So what changed?? (I'm going to list it all!)
Temp last time 72*. Temp this time 78*.
Humidity last time 39%. This time 30%.
Both 29 in-Hg.
Both SAE.
Both corrected to 1.01 factor.
Both smoothing 3.
AFR last time around 12.7 average. This time around 13.3 so car is tuned???
Last time no tune. This time tuned.
99% sure last time 4th gear. Just called dyno guy, he said 100% 4th gear.
Tires last time 29lbs. Tires this time 30lbs.
Last time OEM lower. This time ported OEM lower.
Last time OEM upper. This time ported OEM upper.
Last time OEM TB's. This time ported OEM TB's.
Last time Stillen gen 3 copy, design and pipe size CAI. This time new CAI with more of a straightened piping with filters in the fenders and bigger MAF housing increased to 0.3" in size over old one and tuned for it of course!

And last, the guys said they haven't touched the dyno in anyway since last year.


Ok on to pics and summary. The new dyno looks like it gained absolutely nothing! And remember, I'm tuned now!! ((((I gained roughly 15hp/15tq at the other shop where I was tuned. The difference in the before and after on the day I was tuned of course was the tune and also the new CAI listed above, that's it. So at the old tuner the "base run" was everything that the first IPS dyno was but plus the 4 ported parts.) The lines criss cross today a few times throughout with a hiccup this time at 5500 rpm and it gained some power at 7100 rpm to redline (big deal). Besides seeing the leaner AFR this time you'd think I never got tuned, the CAI did nothing and the porting did nothing. I'm at a loss. I really thought I had it with the gearing.

 

FYI, base vs final tune on dyno day in their weird correction factor. Also my new CAI and tune here.



Their dyno did have a dynojet correction factor setting. Base DJ factor...



Final tune DJ correction factor...if their DJ factor really is like a DJ like I was on today then that's why the TQ are both mid 240's. But then where did my HP go??!
