Y2K are you done all the tests yet? whats up man?

 

RA - Yes, the 239 HP figure is totally stock. The reason for the different figures would be hard to narrow down to one factor. The air temperature/humidity factor's there, as well as fuel quality; state of engine tuning; etc. Probably the biggest factor is Lexus itself. Unless U're running a NASCAR IROC engine that's been built & dyno'ed to yield the same power, then assembly & tolerances play a huge factor. As an example, my friend had an '86 Corvette that made 235 HP ( according to Chevy ) while my '87 'Vette ( when stock ) was advertised to make 245 HP. However, I couldn't beat him nor could he beat me when I drove his versus mine ( to take out the driver ability factor ). Either mine was weaker than normal or his was stronger - both totally stock. That's when I called Lingenfelter!!!! Let me dig up the dyno sheets that I can find or call my friend & I'll post what I have - may not be able to scan them in so if not, ya'll have to trust me on the numbers. :eek:

 

Mean Gene,

23 rwhp difference is a lot in my opinion though there are indeed some factors could affect the result.

 

yea i agree, way way way too mch difference, maybe 7 or 8

 

well you have to understand that HP doesn't = better performance. Just look at the 540I sport manual as a good example. The 540 gives out more HP will when racing the GS4. The GS will take it why is cause of the motor>tanny>chip. The GS was design design very well and again thats why if you add an exhaust. Your not going to get anything or very little.
I believe that the GS is a great car to work on for more performance.

 

Different Dynos will always produce different results. That's why it important to dyno your car at the same dyno. I just got my '98 GS400 dyno'd, baseline 230. With the swift Air Filter/ECU, 241. I'm not pleased at all. I think the best way to go is to get the Apex S-AFC and do a dyno and tune with A/F meter. This way you can get the most out of your car. That's pretty much what the ECU is doing, it's changing your Air/Feul Ratio. You can't change it with Swifts ECU, you can with Apex S-AFC. I got over 30 RWHP on my '97 Supra after tuning the car with a S-AFC. My opinion go with the Apex S-AFC, $300 + dyno and tuning $250, still less than the Swift Air Filter/ECU.

 

whats this weapon r thing Y2K? can you actually change the rev-limiter? i may order one just for that featre!

 

go to weapom r post for more info. but I will say this. the intake from SRT only gives out 11-12HP at most. SORRY

 

Hopefully soon I will do some dyno on my car. Everyone has a large difference in dyno under stock (assuming 16"). It doesn't seem right.

 

whats up guys, i just got back from hawaii. hey, so where is the weapon r post? i am very interested in seeing the results.

 

SliverGSGuy,

Where did you put the S-AFC?

 

i have it hidden in my center compartment under the armrest.

 

Could you please take a pic of it?

 

i cant seem to find my digital camera right now, but when i do, ill take a pic

 

i am looking for more info on the apex-i s-afc meter. is there a significant amout of hp to be gained for the money? i would be installing it in my 2001 gs430 which only has a blitz nur spec exhaust and no intake. can someone please help me out a lil. also, i've heard a little about the weapon r intake. will it fit the gs430? and if so, how does it by pass the factory air sensor? i guess another question i should ask is where can i find the thread on the weapon r intake?

oh ya...one last thing...will any of this void the factoy warrenty???
