Shift at the rpm that's ur highest horsepower. If ur car makes power the same power at 5800 rpm and at 6000 rpm there's no need to take it to 6000. It's wasting time. U should shift as soon as ur car reaches peak power for each gear. All cars are different. A dyno can give u this info.
Totally understand:) I have drag radials and wasnt hooking well! I can hook in cool weather but 39 degrees was too cold. I'll see if I hook next time. I have the same tires as u for the street. I tried them all and love those. They hook pretty good and seem to last so far.
Nice! I was just at island a few weeks back on a friday night. Got 12 runs in! Im going to go one
more time before the season is over. I went with 2 other vipers. Let me know if ur interesting in going this fri or next? Nice runs!
I did Greg good heads and manifold and a comp cam. The car had headers and exhaust. I put 70mm throttle bodies. I'm making just about 600 to the wheels. just get in touch with Greg and tell him what ur goal is. U really don't have a choice! If u want the best u go to mr Greg good. It's pretty...
Thanx for all the help:-) theres so many more factors than i thought! I talked to a transmission place today who said i should change my trans gear ratio's? If i change to 355's with the tall tirethat sounds like it would work for the strip, but when i put my not as tall street tires on it may...
I did 130mph with the 333's not close reaching the end of 4th tho. Time was 11.1 60 foot time 1.996. If I bring the 60 foot down to 1.6 I should be mid high 10's I think?
I know this has been discussed before, but im asking a more specific question. I have 333 gears now. I tried every gear ratio possible in mild modified vipers. I did best wth 333's in those cars in the 1/4 mile. Some people say with 600 rwhp and over 600 torque the stock 307's are better...
Fyi im talking about the underneath! Not any part u can see unless ur under the car. Yea dont spray it if its a scratch u can see if ur standing up looking at the spoiler, dont think that would turn out to good with gloss black spray paint.
I live in n.j I scrape it 3 times everytimes I'm out. I carry gloss black spray paint in
my trunk. My cars lowered too! It's sucks but nobody ever noticed! Shhh! Im the only one who knows! Just for the record if I ever try to sell the car on here, I'm lying and it never happened:)
Garron u have to ask the dyno guy how he has it set up. The dyno I went to didn't correct anything! I did at 93 degrees and it was humid. He said that's how my car runs in that weather. He said to come now to see what it gets in better weather! So I guess that's why they all vary. Like u said...
Yes the dyno is just a tuning tool. On the mustang dyno I only did 507rwhp? The dyno guy said he multiplies that # by 13 point something? He came up with high 500's. I wasnt too sure of any of it until my 2nd run trap speed
Was 130mph! Now I know I'm right around 600rwhp. It's funny cause I was...
After my engine was done it felt strong! I had chris from dc email tunes to my dyno guy. Car was only making 450 to the wheels which was low for all my mods. Felt fast to me tho. 1st pull before sct tune was 450 2nd pull after 1st tune was 550! Ended up just shy of 600 to the wheels. All...
I'll get someone to video it next time and get the idle on tape too. Greg said the cam was a little more radical than what most people use. It might smell like gas fumes at idle and be tricky to drive slow, but I haven't noticed it to be annoying. I had a lot of muscle cars with big blocks so...
Put down 580 hp 615 torque. Then Greg had me change the plugs and gap. The plugs were loose. Tuner took them all out by hand! It was humid and 92 degrees day of dyno run. Greg expects over 600 to wheels. Crazy cam he said:) I'll go back on a warmer day and get a video. Ha it was so cold nobody...
Greg good heads cam car. 11.1 130 mph! Too cold for traction. 60 foot time 1.993! Not too much traction in 2nd gear. Easily a 10sec na car with better weather. Guess u were right Greg. Thanks :)
Gtr's are fast from a dead stop. From 60 to 130 an 08' viper will beat a 2013 gtr! Depends what u like. How often to you get a red light and look next to u and theres a good race? How offten are u doing 60mph on the highway and you see something good next to you?
Greg good is simply one of the best if not the best guy in the viper world! Very very intelligent guy! He has so much knowledge about performance engines its scary! He will take the the time to explain everything in detail when hes not porting a customers heads. He helped me put together a heads...
Re: Are you running a wideband? Is it necessary with a N/A engine, or mainly just FI
I just had my whole engine done with a real radical cam, Greg good heads, manifold etc.'Greg and chris from dc racing said to get a wide band. AEM makes one with a fail safe but it's not out yet so I went with...
nice! I wont have a chance to try mine until my heads and cam get done! Plus i wont have a consistant before and after to compare them! Let me know what ya think? Hope there are good!!!!!
Yeah I looked at some reviews. Still have some concerns. I don't know if I like the engine cutting out and then going right back to wide open? I'll call around to ask questions. I did talk to a trans place that said they could make it smoother. I'd rather go that way, but I'll look into it...
