Julio, Is there something more going on with this alcohol system than we might be aware of? Or at least me. I went to the track today and the weather conditions were almost perfect. The temp. was 50 deg. all day and the humidity was between 50% and 60%. That was 15 deg. colder than last week and there was no head wind as there was then. This temp. allowed me to run an increase of boost to 26# in first and second and then it scaled back to 24#
in third. It makes me think that possibly the decrease in intake temps. at 90 deg. might be linear at 50 deg. also. Is that possible? Is the engine seeing maybe a 30 deg. intake charge with the alcohol? I may be in way over my head on this one. Anyway here are the results: 1.54 60 ft., 7.25@94.33, and 11.45@115.99. The second run netted a 1.50 60 ft., 7.17@94.77, and 11.37@116.35. Boy was that a ride. The last thing that was different was the installation of a RJC boost controller. That little piece of brass is unbelieveable. I thought my turbo spooled up fast but nothing like that. On the trans brake from 5# to 25# is almost uncontrolable. A different launching procedure will have to be learned.

Its just to say it again. Alcy has moved the limits for us. For a couple of years ago was 12.2 a magic number for a stock turbo. Now it still a good number but as you all see a 11 can be done several times. 110-112 mph was the max speed, now we see 115-116... All these runs are made on alky.
Makes me wonder... someone told me a year ago that for a TA49 11.7 is the max. I would say a low 11 is reachable nowdays with a 49... someone that agree with me ?
If I only can tune my car in... 8.25 seems slow for my combo lol. Maybe I take Julio to Sweden next year.

Eddy, are you using a stock wastegate actuator?
You might want to consider going to an 18psi springed one to see if that boost will stay at 26psi for ya.
What ignition timing are you at, might want to consider upping it a tad since the outside temps have dropped.
Ever thought about getting a 3000 Precision Converter?
It has the most K factor out there and could probably drop off another tenth for you.
Are you using the new MT Street Drag Radials?
I am not ditching my TA49 till I pass 11.3 now![]()

The alcohol cools the heat generated by the stock turbo.

Like Razor said.
I'll elaborate:
Which allows you to run a small turbo, lower stall,no race gas, lower injecter DC, ......Like a domino effect. leaving money in your pocket for other things like slicks and suspension parts!
