VICE Posted January 5, 2008 Report Share Posted January 5, 2008 flat tops :shock: yup, we don't like flattops here Who's ran them and had a catastrophy that wasn't tuning related? Hey is that a carbon fiber hood or what? Link to comment Share on other sites More sharing options...
Blind_Drifter Posted January 5, 2008 Report Share Posted January 5, 2008 ^^ No. Its flat black. But there are carbon fiber hoods being made. Contact 101purpose Link to comment Share on other sites More sharing options...
VICE Posted January 5, 2008 Report Share Posted January 5, 2008 I wanna get me one with the scoop and the 2 vents on the side to let out all that hot air and RAM AIR some more cool air in.. Link to comment Share on other sites More sharing options...
Blind_Drifter Posted January 5, 2008 Report Share Posted January 5, 2008 The one 101purpose make sis the 83 style hood . You could cut the vents to be functional. Link to comment Share on other sites More sharing options...
JustPaus_88TSi Posted January 5, 2008 Report Share Posted January 5, 2008 The vent locations in the 83 do not promote any kind of heat extraction, they're in the wrong pressure zones. :wink: Link to comment Share on other sites More sharing options...

VICE Posted January 5, 2008 Report Share Posted January 5, 2008 Hmm what if I cut out a vent right on top of the turbo on a stock hood? Link to comment Share on other sites More sharing options...
BOHO Posted January 5, 2008 Report Share Posted January 5, 2008 The best/easiest heat extractor mod that I've seen is on the CINquest....He cut a hole about 18 in....right behind the engine on the fire wall. Vents off to the wiper cowl....looks good. He left a lip so the water would still run off properly... Link to comment Share on other sites More sharing options...

JustPaus_88TSi Posted January 6, 2008 Report Share Posted January 6, 2008 The high pressure zone at the base of the windshield would force air in, not allow it out. :wink: Like how a cowl hood functions, without the looks of the hood. Good stuff. The best? No. Still very functional? Absolutely. Extracting heat from the engine compartment would best be done by one or two parallel vents(roughly 18-20"x2.5-3.5") placed in the center of the hood, with the first vent starting about 14" back from the front point of the hood. Search my name for "extraction", or "magnehelic" or "manometer" for older threads about it. Link to comment Share on other sites More sharing options...
Elkidmino Posted January 10, 2008 Report Share Posted January 10, 2008 flat tops :shock: yup, we don't like flattops here Who's ran them and had a catastrophy that wasn't tuning related? Wellllll, Gober803 ran 22RE pistons on his destroked motor, you might remember that. Problem was, they were N/A pistons and didn't like heat. He raced a bimmer one day at 25psi, leaned out and BAM! number 3 piston turned into 100 pieces. Rod bent and crank was fine. Otherwise, with his SDS system, we had the thing rough tuned at 20psi and it ran like a bat outta hell! http://www.26liter.us/gallery/albums/userpics/10121/IMG_2751cr.jpghttp://www.26liter.us/gallery/albums/userpics/10121/IMG_2755cr.jpghttp://www.26liter.us/gallery/albums/userpics/10121/IMG_2759cr.jpghttp://www.26liter.us/gallery/albums/userpics/10121/IMG_2760cr.jpg I flipped a lid the first time I saw that. And yes, it was an interference motor like this. Link to comment Share on other sites More sharing options...
JustPaus_88TSi Posted January 10, 2008 Report Share Posted January 10, 2008 Ah yes, I do remember him now that you mention it.. It's all in the tuning, it has to be dead on when you run a CR like that with higher boost and who knows what kind of gas.. You're description said it all though.. "Leaned out at 25psi etc.." Sounds like a tuning issue to me. NA pistons, a much higher compression ratio, big boost and a "rough tune".. Come on. Throw some forged units in there, give it a dyno and road tune(more load created on the road) and you'll be alright. After reading one of his posts, he had the pistons machined to reduce the dome's.. No wonder they were weaker. I still think a "true" 8.5:1 CR would be fantastic in this motor. Link to comment Share on other sites More sharing options...
Elkidmino Posted January 10, 2008 Report Share Posted January 10, 2008 Your correct, those radius's in the pistons were helping to create detonation spots while under boost so he had them machined down to flat tops. Also, rough tune is right, no dyno tuning, just a week straight of driving around changing values till it hauled all and didn't detonate. :oops: We were ignornant then.... Side note: Ran a Fel-pro HG, HG was fine when the head was pulled. Link to comment Share on other sites More sharing options...
Bad2Rass Posted March 3, 2008 Author Report Share Posted March 3, 2008 almost running with the new bottom end hopefully by the end of the week I will have her going!! Link to comment Share on other sites More sharing options...
Bad2Rass Posted March 10, 2008 Author Report Share Posted March 10, 2008 Well it runs and it runs really well. It seems to have an insane amount of torque. I like it. Link to comment Share on other sites More sharing options...
Bad2Rass Posted April 11, 2008 Author Report Share Posted April 11, 2008 (edited) Ohh yeah put in a secondary injector as a primary and tuned with MAF-t. I Have it set at like 18 psi now and it stays steady in the 10.5-10.9:1 AFR neighborhood so I think it will be good for a little more boost, Maybe 20. But as of right now it feels a ton more powerful than it did with the other engine at 24 psi which made 296 to the tires, no dyno sheet for that one but i have many witness'. Can't wait for some DYNO time on this engine. Kyle :hmm3grin2orange: Edited April 11, 2008 by Bad2Rass Link to comment Share on other sites More sharing options...

Bad2Rass Posted April 15, 2008 Author Report Share Posted April 15, 2008 going to put it on the dyno today maybe i will make some really big power but we will see. Link to comment Share on other sites More sharing options...
Bad2Rass Posted April 16, 2008 Author Report Share Posted April 16, 2008 Just got home a little while ago had some time on the dyno this afternoon over at top speed performance along with the AAM crew. Here is the graph highest number was 305 hp and 276 tq. The lines seem to follow an odd line for the 2.6 but maybe a tighter exhaust housing will solve this problem. The lower number was at 19 psi the high number was at 23 psi it feels insane at high rpms http://i45.photobucket.com/albums/f65/bad2rass/kylems.jpg Link to comment Share on other sites More sharing options...
