If possible I would like to see some of your dyno graphs with the aps f-body kit. Also please include your other mods somewhere in your post. I am trying to decide between this kit and the magnacharger kit.. I am concerned with how the low end power looks on these.

 

Magna charger will make instant tq and power. Turbo cars do not. No dyno sheets needed.


PS: APS > Magnacharger

 

It will have an impressive torque curve but not like a Magnuson.

 

i am aware it wont be exactly the same, I am curious to see some graphs to see exactly where these kits are hitting strong torque numbers in the rpm range.

 

I'm sure you could build an APS set-up to see full spool by 3k rpms. Who races below that anyway????

 

i agree, thats why i want to see where ppl are at.

 

I dont have a graph. but I'm at 605rwhp 622rwtq @ 7psi.

Its a Katech 402 low comp motor with the APS kit. Need a better clutch so I can turn up the boost. This motor really doesn't like the lower boost level. Needs to be at 9-10psi . Thanks

 

Like Torque?



Here is a link to his build up, http://www.exoticperformanceplus.com...Car.php?car=39


402ci , AFR heads ,FAST 90 , aps TT.

This thing is a monster on the road.

 

thats what i want

 

wow... Jake thats at 9.2 psi it says?? thats awsome!! cant wait to strap mine down...this gives me inspiration...lol

 

A few things to consider. Too much low end too soon is not that useable unless you are going to run like et street radials full time. Even nittos aren't that great once the big power numbers start happening. So turbos that spool up a bit higher up may be a benefit and you stay out of boost mabye a bit more,helps mileage and gas is getting more expensive every day. Also maybe stay out of trouble..tickets and the like are also getting more expensive every day.
One reason why ati can be good on the street. They build boost as function of rpm.
The maggies do come in very low but not sure they compare to the turbos up high and if many of them can do the same power numbers the turbos can. For a guy looking for likely 500 to 600 engine don't think that much difference between a maggie and turbo.For guys looking for 1000 engine or beyond then the turbos are likely the best choice or big ati centrificals.
Also not sure about this but think dynojet or other non loading dynos won't show proper spool up on the turbo cars. They don't load it like street or load bearing dynos like mustang. Would think mustang or similar type dyno would show better. Also heard auto dynos can throw off numbers do to flash of the stall.

That said I have had rides in most types of power adder cars. 500 engine hp NA f bodies, STS ls1 and lt1, Nitrous third gen and some old muscle stuff, own several turbo cars. And used to own a rat motored 6.71 supercharged car. Rat being a punched out 454 chevy big block.

All power adders are fun and all work pretty good although of course a bit differently.
And sometimes the theory and the reality are very different. Like what I said earlier. You might want killer torque right off idle but on the street if you can't hook it whats the point,it could even be dangerous in bad weather especially if you don't have things like traction control.
Also there are tricks. You can gear down in manual cars to bring boost up sooner. You can use things like two step to get boost off the line. Auto cars can use stalls of course to get more boost off the line.

 

dyno only one day away

 

My dyno graphs from when it was tuned.
