Ran today - stock times inside

[HotAirPrime85]

well not completely stock but pretty much, autometer boost gauge, got a cone style filter and adjustable wastegate rod but set to same length as stock (and boost is same as when had stock rod) ngk UR5 plugs and a 160 thermo. pushing about 8#'s ran 15.6@89mph 2.4 60ft (skinny street tires) had my m/t dots, but my pit crew (lol one dude) messed up a lugnut on passenger side so i couldnt swap em out. so im ready to start some real modding and see what i can do. plus it was in the 70's today, so with some better weather and sticky tires i think i can hit 14.9's if i try real hard

What was the boost set at?


Your times sound just about "on par" with a Stock Hot-Air car....Mine ran 15.5 @ 88........after spending some money...it now runs 12's (hope to have 11's real soon).


Have Fun with it!

its was set to where the stock length was. putting out 5-8#'s normally it spikes to about 8 and settles to 5# i want to up it but i need to get a few things before i do that so i can do it safely. im hoping with some better 60 ft times and not spinning that i can better than ET a lil bit

Son, if you're running 8 pounds of boost, that car is gunna be a dog!

Stock boost is 12 psi, shorten that wastegate rod 1 full turn per pound of boost you want, a stock turbo will reliably make 14-15 without knock if your plugs and fuel are good.

and make sure them UR5 plugs aren't fouling since they're a bit colder than the CR43TS plugs, which are already a range colder than the stock plugs!

also spend $60 and get a knock gauge, takes 10 minutes to install, and wil help you save a headgasket possibly!

the boost has gone higher when i was first tuning with the adjustable rod, but i didnt wanna push my luck yet till i know if my fuel is gonna be enuff to cover it. and a knock gauge is next on my list

dude... i'm running 15-16 psi. and i rod the piss out of my car..crank it up man, you wont regret it.. see what 12 psi gets ya, you'll be impressed.

Stock fuel pump is plenty until you start running more than 17 psi boost and upgrading turbos etc etc, but if you're still stock, crankt he boost up to 15-16, good gas you really wont see much knock at all if everything is in ship-shape. start at 14 and work up until you feel its too much..

I was running 22 to 23 pds with the stock turbo and stock fuel pump on 110 octane with slight knock/miss at the end of the track. I didn't even have a hotwire, but this was before I knew better, so its alowed. Put some high octane in it and crank it up. I ran a 14.3 at 93 mph with no mods except an adjustable wastegate. The tranny was slipping real bad and it was starting to knock or miss I don't know witch one. I believe miss cause I replaced my coil and it went away. I fixed those problems and ran a 13.9 with hardly an mods.

dam yall got me wanting to go back to the track already lol, im gonna turn it up a lil more, knock gauge ordered, fuel pressure gauge on friday, and sticky tires

Just make sure your monitoring your car when you start to turn up the boost. Might want to wait till you have that knock gauge and FP gauge installed before you start cranking it up. All of our cars are different, and you never know what potential problems may be lurking.
Everyone wants more boost, but if you have no way of knowing what its actually doing to your engine (i.e. scantool) its like playing with a timebomb. Be safe, not sorry .

Just my 2 cents, good luck.
