my baseline dyno before TT (Rev-up)
my baseline dyno before TT (Rev-up)
Posted this also in the engine/drivetrain forum for their reference for N/A applications. But this thread posted in the F/I forum will be updated after the APS TT and the SFR custom 3" HKS Carbon Ti true dual has been installed along with the goodies listed in my sig.
Here's my 35th anniversary's baseline dyno. Kinda weirded me out because the hp and tq is showing a bit low for the rev-up engine.
238rwhp / 225rwtq
This was done a nil elevation in 5 degrees celcius weather. Kinda foggy so it's pretty moist. This was done on a dynocom. (www.dynocom.net) is made in Canada, so I'm not sure where to place this. My tuner said it should be more towards the mustang dyno numbers.
I only have the Injen CAI and the JIC single exhaust installed for this dyno, which should all contribute to a higher top end. So I'm pretty disappointed. Could be due to the fact that my car only has 1800 miles on her so far tho.
anyways here's the dyno chart. Let me know what you think.

UPDATE! impressions of the exhaust. (also posted this in the intake/exhaust section with pictures)
Just bolted on my SFR custom 3" HKS Carbon Ti true dual exhausts with my APS twins. Here are some impressions.
The piping of the SFR system is not fitting too well, especially around the M-brace area. Had to modify it a bit, and add a spacer on the M-brace to clear the SFR true dual so it wouldn't rattle against it. Slight hiccup, no big deal.
Here's the thing. The APS TT was bolted on, with my old JIC single exhaust and nothing else, and dynoed on a dynocom, which according to my tuner, has to multiply by around 13% to get normal dynojet numbers. So for the sakeof comparison, I will type out both numbers. Keep in mind I have a Rev-Up engine, so I might take mods slightly better.
Some of you might have noticed my post of the nice pink dyno chart before. That was my baseline...with Injen CAI and JIC single exhaust.
235rwhp 225lb/ft rwtq (dynocom)
= approximately 265.55rwhp 254.25lb/ft rwtq (dynojet)
After APS install, still with the JIC single and factory cats and y-pipe:
386rwhp 398lb/ft rwtq (dynocom)
= aproximately 436.2rwhp 449.74lb/ft rwtq (dynojet)
I was satisfied with those numbers already, and couldn't hope for better...until I bolted on the SFR true dual.
APS TT with SFR true dual without anything else. No tuning yet either:
430rwhp 404lb/ft rwtq (dynocom)
= approximately 486.7rwhp 456.5lb/ft rwtq (dynojet)
The baseline dyno some of you have seen already in the above mentioned thread. I do not have a dyno chart of the APS with JIC exhaust, but was told the numbers by my tuner. I do not have the dyno chart of the APS TT with SFR true dual yet. My tuner said he will send me that tomorrow. He just told me the numbers. Keep in mind my tuner HATED the SFR true dual cuz the piping needed some modifications to clear everything, but he was totally shocked with the results as much as I was.
The numbers above are all generated from dynocom, except the dynojets numbers which I calculated by multiplying the dynocom numbers by 1.13. Of course that is an approximate number. Not used to claim anything, but better as a comparison. That's why I posted all the numbers before and after the installs.
Tim (turbotim) at SFR was a pleasure to deal with. I was in need of a true dual in a hurry, he manufactured me one RIGHT AFTER I called and got it to me in a week. So the customer service is excellent.
This is a very well designed kit. Free flowing, reduces backpressure. Ideal for TT kits with huge amounts of tq, to tame down the tq a bit and increase top end power a lot by producing an exhaust with barely any backpressure. I'm thinking if the dyno came out like this, showing the lack of backpressure, I don't know if this would be a great exhaust of N/A applicatons. But for F/I, definitely.
Although I might add...the JIC may be better for N/A applications due to the backpressure. Too bad I didn't dyno both exhausts in N/A form as well.
I hope this answers some of the questions you may have about the new SFR kits that most of us are unfamiliar with. Just knowing it's with 2 HKS Carbon Ti's is not enough to purchase a whole exhaust system.
Feel free to comment on my analysis. I will post up the final dyno graph as soon as I get it from my tuner.
