IS-F Tune Released

You seem to be basing your assumption on vehicles with similar HP,TQ, and displacement size. Just because other cars have similar spec's it doesn't necessarily mean ISF will responded in same fashion as e93 or Mustang when tune is added.

I will try to demonstrate how ISF may indeed be able to produce more than 20hp. I will not use my personal opinion or make assumption what I will do is use facts about car you have mentioned more than once to compare against ISF and that's Mustang. You keep bring up Mustang because they both use 5.0 motor make similar HP/TQ and both make power in similar power range between 5000 to 7000rpm but that's where the similarities end.

ok some basic info on ISF with I/H/E they have been dyno proven on average to make between 400hp and 406hp some making less other making slightly more but lets go with average 400hp to 406hp range. 1/4 mile times with street tires low to12's 12.09 to 12.30 with drag radios high 11's 11.80 to 11.90's. These numbers are fact they are not my opinions nor assumption or wishful thinking they can all be verified, so now that we have established some base line numbers lets take look at Mustang and not 2008 4.6L motor which is yr ISF came out but newer 2014 and 2015 Coyote motor.

2014 Mustang Coyote Motor
base line dyno 360rwhp/356tq
After tune and dyno 373rwhp/368tq
Muscle Mustang & Fast Fords took stock Mustangs and did build using only bolt on parts and tune but NO SC or Turbo was used they did not disturb stock block or Transmission internals. Here is the list of parts used
Ford Racing Performance Parts
Cobra Jet intake Manifold, FRPP throttle body, CAI, Stainless Steel Long tube headers, full exhaust, FRPP 4.10 gears and JMS/SCT tune and updated suspension.
After all parts install 413rwhp now ISF with just I/H/E 400 to 406
Stock GT 1/4 run 13.24 at 107.68 after bolt ons and tune 11.94 at 116.98
Stock ISF 1/4 run 12.54 at 117.20 after bolt ons I/H/E 11.91 at 120.58 this info was taken from drag times.

The reason why I posted this up was show how the ISF with just I/H/E put out nearly the same horsepower as the Mustang with Tune and nearly all bolt ons and traps similar 1/4 mile times.

They also swapped out torque converter and went with pro series stage 111 258mm aluminum converter, carbon fiber drive shaft, and set of comp cams XFI stage 3NSR camshafts

When done total was 433rwhp 353tq. I think the ISF with tune should make similar HP.

2015 Mustang GT
Bama Performance
base dyno run [B]381rwhp 359tq
after tune 402rwhp 382tq
CAI, tune 412rwhp 382tq

To me this show that there maybe just bit more left in motor, and I believe they will be able to extract more that just 20hp from tune. Lexus and Toyota are know for over engineering their vehicles if they do it to the motors why wouldn't they do same thing with its tuning ability. When they build there cars they tend not to max them out, they leave some room for safety. What will the final number will be? I don't know, but we will find out soon enough. Either way its win for not just ISF but all cars from Lexus RCF, GSF, IS350 it gives enthusiast another choice to choose from, and with Supercharger kit under development that should be available in few months puts into a whole new class of cars that it can now compete with.

For me it's ability of using forced induction or changing the cam's etc is what makes this so important. The over all goal was to be able to add SC or Turbo etc any bump in power is nice but not the main goal for this tune.

I agree hell my base line dyno run on my stock e90 was
343whp 251tq
after bolts on and only 240e software the car made
367whp 262tq
after tune with frank the car made
381whp 276tq and thats out of a lil 4.0

[QUO19330806]8600RPM It's just using common sense and a little bit of basic engine understanding. I'm sure dynos will roll in. I'd venture perhaps the isf can squeeze a but more aggressive timing advance due to direct injection and port injection but on pump gas you won't see more than 20 hp off a tune.[/QUOTE]

Just quick up date recently ISF owner on CL dynoed his ISF with RR RACING tune, factory headers deleted cats, custom 2.5 in x pipe with borla mufflers he made
433rwhp 376tq. RR Racing claims with aftermarket Headers expect additional 6 to 10hp. RR Racing getting ready to release larger 87mm MAF, tune intake, larger 79mm TB, Reconfigured cold air box. They haven't Released any horsepower numbers as of yet, they're saying there will be significant increase if you have aftermarket headers installed on the car. My feel is 6 to 10hp increase, we'll have to wait and see.

When my ISF had just catback I ran my friends 6spd 3 times beat him each time, when I be ran my other friends DCT from dig has advantage lighter and damn FAST DCT lol, From roll super close each time, both cars are fast they just go about it differently.

Now back to original OP, yes after 8 years of waiting final crack ecu, 405 was done on RR Racing ISF it has secondary cats removed and primary cats gutted. Now what was interesting is this dyno is know for lower numbers they are very conservative with their hp/tq numbers it reads 20 plus hp lower than most dyno's. Their was also another ISF with I/H/E his base dyno was 380hp, his previous dyno run at other dynos netted him 400hp. So they new that 20 plus less hp was pretty accurate. When tune was installed and he did his pull he netted best run of 411hp. So there looking at around 430hp on most dyno's, Not bad for some bolt ons and tune. There still working on it, some thing's they currently working on 80mm throttle body which they tried but due to large increase in air flow they're going to rework the map. RR Racing also has SC kit for ISF over 600hp they also may develop cam for it as well. RR Racing actually race's ISF so they have tons of experience with platform and have been working on the tune for 5 months. Currently beta testing the tune on westcoast, midwest, and south.

Dynojets are not known for being conservative. Quite the opposite in fact. Mustang dynos are the conservative ones.

RR Racing Tuned Intake Results

I still kind of feel like...for the advantages the ISF offers over the m3...much more torque, more hp (modded), the sound of a larger v8...you may as well get the c63AMG and get those same benefits x2.

The nod still going to the ISF for overall reliability.

Great gains nonetheless.

Hi guys

TTFS Shop ISF - Yes we are tuning Lexus now

I think the appeal with the ISF is because it does most everything well...and also it's a rarer car.

If you choose a 2011+, it has the handling limits on par with an E9x M3, sound and power of a C63. and the reliability of a Lexus.

As a bonus, I know most buyers in this segment could care less but it gets pretty decent gas mileage for a 400hp+ V8 sedan, 25-27mpg highway average if you're easy on it.

If the C63 AMG exhaust note is your thing... you can slap an H&S exhaust on the ISF and Enjoy.

Wow. That does sound amazing

Don't mind me...just gonna go look on the Lexus lot...not gonna buy anything..just look

I prefer the sound of PPE headers in combination with the Joe Z exhaust.

i love the looks of the IS-F. if i had to buy one v8 performance car out of warranty it would be the lex. that blue lexus has is... awesome

Here's interior video clips of my 2011 USB IS-F with PPE Headers and JoeZ exhaust shot if with my cell phone.

Looks like tunes are working out great on these cars.

IS-F running 11s with only header/exhaust and tune. On street tires.

Needs a manual 6MT or is not worth buying.

[8600RPM]

E92 m3 runs high 11s at 118 to 120 mph when the are catless and tuned

Funny considering what makes the S65 great is it coupled with the DCT gearbox. That 6MT is mediocre at best.

Incorrect. But whatever floats your boat.

[FFM]

Lol, I knew that would stir the pot, and yes it's true to those that can see passed the third pedal bias. It's superior in every category, except drivers personal preference, which then is just an opinion of which can be the wrong one technically

No pot stirring here. I honestly don't care what your preference is and this topic has been beaten to death as I'm sure you know. As someone who has extensively driven both, I just think calling the 6MT mediocre is ignorant at best and really just highlights your own bias. Both transmission choices have their merits, subjective and objective, and if you don't recognize this then you are blind. Not sure why you would even bother trying to "stir the pot" on this topic (or why I'm even bothering to respond).

[FFM]

It's really not that great, but when it's one of two options and the other being no third pedal I get why it could be perceived as acceptable. It's pretty middle class compared to other gearboxes. Compared to say the 6MT in the Honda S2000 which is one of the best manuals ever it's a night and day difference.

I love the E9X, it's still one of my favorite cars. Just because I bought the ISF as a daily instead doesn't mean I'm biased towards one or the other like what typical ownership bias would indicate. I hope to snag one as a weekend toy in a few years, in DCT of course haha.

[davcrz5]

Just update RR RACING has released new intake with much larger 87mm MAF that's mounted into custom titanium mount, with some carbon bits looks nice. Here a little teaser video of their supercharged ISF at Pocono Raceway chasing down a GT3 they're running a shake down car they haven't released any numbers as of yet.

In 5 years on this forum, I have seen only one such result posted, by DLS5, and that was with a DCT car on drag radials. Seems like it should be possible, but does not seem to be often achieved.
