When he had them do the harding process they also added a special pixie dust coating it reduces weight by 30% and adds about 50% duty life cycle to the product.

What gear did you do the 37-104 mph dyno run? I didn't think they were strong enough to handle 700+ WHP.
What is up with your graph? hp and af ratio? It doesn't relate to the powerband at all and most dyno sheets for an untuned engine aren't nearly that smooth. Thats better than most tuned dynos I have seen.
about the dyno pull, it was hp and tq, not afr. the pull was in 3rd. and the car is tuned. i dont know who told you the car wasnt tuned. the reason im going for another tune is to get out all the final bugs and just to get a proper, reliable tune for daily driving. right now on the street i run pig rich and on the throttle it bogs, so just for the bugs.
I guess I just don't understand how the HP curve can be smooth and the torque curve jump around like that. They are derived from the same source.
Normally the street tuning comes first, but I guess whatever system you are running doesn't base any fueling on normal driving for wide open throttle.
Yes, I run the store on this site.
the hp cure will always me smooth if tuned right. the jumps in the tq curve are most likely caused from misfires or irregularaties in the dynomometer it self. reminder it is a clayton dynomometer, not the best, but did the job. also, we had the street tune, but ive modified since then so theres new things that have to be adressed like new injectors.
we recently just converted the sysyem to low impedence injectors and are using RC 95lb injectors, and im hoping i might have the throttlebody by the 22nd for the tuning. ( i bought it from your store, awsome product, seen it on a grand am.)
also, about your store, ive always had guys come to me asking for throttlebodies and cams and such, and i always recommend them to check out your website. so i hope im heloing you out.
Brad showed me that. Id like to see a performance dyno sheet.
Even if they don't get the parts here, I am sure this site helps them out. I appreciate all the business I can get as it helps with new parts 22nd should be no problem. Ill know more in the next couple days.
What ECM are you using? Your current injectors are huge and I dont know how it will idle (maybe 2000 rpm?) with 95 pound injectors. What is the min pulse time?
I Know all about hardening, heat treating and hard anodizing. I know its important. I just don't buy into taking a transmission and applying double the rated output. The transmission is just to small.
The 35 gets closer with numbers like this
Maximum engine torque: 200 lb-ft ( 271 Nm )
Maximum gearbox torque: 258 lb-ft ( 350 Nm )
I don't buy into the bull. I know that you can put about 270 Torque to the 23 but hardening doesn't add 3 times what the stock rated for this trans is
3x170= 510lb-fts\ torque your putting about double the designed load on that transmission now I haven't cracked one of these open, but I can tell you its not going to last to long at that number.
If it was good enough why didn't the SS Cobalt get it??? what the mechanical engineer is a jack ass and didn't go to school for 5 years to design, do load tests, prototyping, and complete a production model.
do u have more info on your headgaskets u used? also more info on your rods and bearings, i plan to run high horse with my built 3400/3500 hybrid, but im still lookin for some parts yet.
hey the head gasket is a copper o-ringed and receiver grooved system. the gasket is available from clark specialty gaskets.
-the rods are a Cat-power H-beam 4340forged rod, 5.7 length, basically a sbc rod.
-the pistons are Diamond forged pistons, which have been ceramic coated, has oil shed coatings on the boddom and sides, and the ring grooves have been hard anodized.
- the rings are a Total Seal gapless 2nd race rings and low friction oil rings.
the turbo's are: for the street is an innovative sh-46 with a stage 6 wheel, 63MM NON-PORT. 50-1 trim.
the big turbo is a GARRETT GT4094R.
but if your looking for somthing that is streetable then look into the innovative sh-46. if you give OLA a ring at innovative turbos, just ask him about the turbo he supplied for imanpreet sehmbi's malibu.
-the crank has been nitride coated and heat treated. the heads have a full p&p.
"Ignoreance" first off. like is said in an earlier post... the car doesnt stay put at 700+hp. thats a once in a blue moon deal. the car sits at usually 15-18psi at max. and at that i see about 400 or less.(well usually less like 370 or so) thats why its still in one peice. and i dont know why the gm guys didnt use it in their cobalt. maybe better design in the new one???? thats nothing that matters to me. i didnt spent millions of dollars and 3 years just to design my tranny, all i did was find a 5 speed that i could swap, and built off ot it. also, if you havnt noticed, many car companies rate their transmission based on clutch capacity. but i could be wrong (well, pretty sure) but hey, just goes to prove how much the tranny can take. so im not saying that im bullshitting about anything, it just held up so what more can i say. and the gears were heat treated NOT to hold the case together, but just so the gear wouldnt snap under low speed, high power acceleration. and besides, if youve ever taken apart one of these transmissions, there pretty well designed, and by the looks of it, theres a lot of braces around the bearing journals. but thas all i can say, so when i do break a transmission ill let you know then you can bitch at me all you want
this is taken from a site i found, looks like the transmission actually is used it a cobalt. !!! but then again it doesnt state the trim of the car so i dont know about supercharged and non.
