Here's my first quarter. I had some spin and TC intervention which hurt my 60 ft. I'm pretty happy with my trap speed.

Here is my first Dragy run. Visconti E50 tune, Injen Evolution intake and CG Precision catted downpipe.

My point in starting this thread was to inform people that e25 is perfectly acceptable to run without any tune mods. This is especially advantageous in places like California where premium is 91. Mixing e85 to achieve 25% ethanol would raise the octane to 93+. This would allow CA cars to produce...

Here is something that surprised me. BMW has been recommending E25 fuel since 2014. It is in the owner's manual.

My son recently got a 2018 C43 AMG. I was surprised at how much harsher it is than the Supra. Everyone who has ridden in my car has commented on the comfort. I know a guy who owns an exotic rental business. Just for fun I had him drive my car and compare it to his fleet: 911 Turbo, Ferrari 458...

I don't know if this was already mentioned but try driving another Supra to see if it is the same. You obviously are a minority of one who thinks this car is excessively noisy.

150+ whp puts it into exotic car territory. My son drove my car yesterday for the first time since my tune and said it is faster than the Ferrari 458 he drove. As far as sound goes, the downpipe alone opens up a lot of sound. I have a 5 inch CG Precision catted dp and I wouldn't want it any...

This will give you an idea of how a lightly modded Supra will do against a ZL1 with boltons and e85. Skip to 11:40.

20th century vs. 21st.

I did some calculations to compare Supra gearing to that of the typical musclecar I grew up with. Overall gearing in 1st gear for the Supra is 16.56:1. The typical musclecar 4-speed stick from 1970 had a first gear ratio of around 2.56. "Close ratio" boxes had 2.20 1st. Rear end ratios ranged...

The door edge guards work up to 65 mph with the driver window alone or both windows open. Interestingly it does not work at all with just the passenger window open. Also, above 65 the effectiveness rapidly diminishes. Given the incredible torque with the e50 tune it is difficult to resist the...

Ecutek says their Performance Analyzer is as accurate as Dragy. Has anyone compared? My new Ecutek e50 tune gave me 100-200 KPH of 7.18.

After all the ooh's and ahh's the bottom line is that the current HKS mushroom filter results in ingestion of hot, poorly-filtered air.

Coincidentally yesterday I was chatting with a friend who owns an independent repair shop. He happened to mention that his brother-in- law has a new Lexus. When driving up a grade the cruise control shuts off. The dealer acknowledges it is not normal but doesn't know what's wrong and can't fix...

In the grand scheme of things it only matters philosophically in that it is a pointless endeavor.

I've monitored oil temp using my MHD app. Oil temp correlates quite closely with the dash temp gauge. Once that gauge registers four bars oil and water are at operating temp. The comment above about warming the engine up in the driveway harkening back to the days of carburetors is absolutely...

My car has an e50 tune. R888R's in the rear are a huge improvement over the stock tires. They definitely "sing" and I wouldn't put them in the front for that reason, though you quickly get used to the sound from the rear. Adding "road-hugging weight" went out with the Pinto. Also bear in mind...

The 30 series tires are more than an inch smaller in diameter. Aside from looking weird it will probably throw off your speedometer and all the other systems that depend on accurate speed info.

Correct.

Those Toyo's are definitely NOT recommended for the conditions you describe.
