You have a link? Anthony said he took one of the motor, but my car was gross that day haha

in for results!

I think this is it man someone took it while they was at performance.370Z long tube headers ---> 350Z HR? - Page 2 - MY350Z.COM Forums

Haha interesting. There are a few on performance motorsports Facebook as well but don't really show the headers.

Chart will be posted tuesday by the latest but again picked up nice power. (20whp 8tq)

From 4500 on. Not sure. What power came from what between motor swap throwing tune off maybe? To the headers ? And flywheel? But regardless they did make power that was shown on dyne and felt my me driving.

Track will be next. Maybe Wednesday of this week or the latest next week sometime

^^^ What dyno? If dynojet, would you mind emailing me the drf's? I can make whatever graphs you want :tup:

Click it than hit the little magnifying glass on the bottom of the pic for a full size pic

lmk if u have trouble seeing it in full size, but if you can filter out the black top A/F line with your eye and look at the TQ curves which are very bump you can see they are much improved as well as the HP showing great gains .... at the bottom states max power is now 330 and was 310 peak tq was 242 before was 234....


My car on this exact dyno at performance motorsports just last year put down a ton more power but it was recalibrated since... I really dont think my car has lost a ton of power.. i have a chart of the old graph on top of this one and from start to finish it was higher,,, im guessing it was re-calibration that caused it as the only other variable was my wheels... i put down 342 with test pipes , etc last year and baselines 310 this year.. as for a mustang dyno the 342 didnt really make sense... there is no way I lost 32 horsepower as my trap the last time I went to the track was higher than ever... it would of shown a significant drop if i had 32 less HP

but from the original baseline with last years mods 310whp rose to 330whp with the PPE Long Tubes and flywheel + retune... they said without the tune it was still in the 320's

If the dyno was re-calibrated that is exactly why your car went from 342 to 310. You didn't lose any power.

And, BTW, that is why I always say that Mustangs can break hearts OR lift spirits -- depends how it's calibrated.

So, just to make sure I am following: You were putting down 310 with test pipes and a tune before and with a re-tune are putting down 330 with PPE?

When was the 310 baseline taken?

Love to see what your car puts down on a dynojet...

yes jordo that is correct... 310 to 330 ... the dates are on there... it was about 5 days later.. was supposed to be the same day but due to issues with the LTH install and prior out of state appointments for tunes it got pushed back...

That's a nice gain over test pipes -- about a 6.5% bump in peak power. That's really good! Congrats :tup:

Im not trying to hate, I would love to see some new mods that prove gains, but this before and after is not accurate,

Its test pipes VS headers and Tune...

the tune alone can give 20 HP.. unless i missed something..

That's very unlikely... also, keep in mind that the previous tune will not be optimized with the new headers, therefore it still gives you a good idea of the approximate percent gains over test pipes that could be achieved with them (and a tune).

If we want to be ultra conservative about estiamtes though, I'd say probably 2.5% of the gains are from "just" the tune. That fits what his shop claimed where the car was in the 320's before additonal tuning.

So figure about 4% without tuning, which is still pretty good considering that's over and above any gains realized from TP's.

Actually, Chuck, what are all of your mods?

The car was already tuned before but was running a bit rich. Before the retune she was in the 320's so power was gained over just the test pipes. The retune did not give 20 hp.

My mods are stillen g3, ppe Lth , stillen exhaust , Fidanza flywheel , and 4.08 FD.

The headers without a doubt added nice power. It was instantly noticeable.

awesome bro!

hit the track now!

I'm seriously considering this brand for my Z seeing it's of good quality and isn't over priced.

Hopefully all goes well with my install on an HR...

I have a set of these in my closet that I need to get on my car -- nice pick up.

Looking forward to a vid if you have time to make one :tiphat:

Hey guys quick question here. For anyone that has installed LTH, how many O2 sensors you use? Do you still use all 4, 2 upstream and 2 downstream?

My FI LTH's use all 4 O2 sensors.

Same with PPE LTH.

The dead thread has arisen!

Thanks guys just wanted to make sure
