PTE 6466 first impressions

[turbo nasty]

Just getting my new build going/driving/tuning drivability and loving this turbo. Coming from ported irons and a 6262jb to TA SI heads and a 6466 BB...now granted there's more airflow but with same cam, stall, etc the turbo spools like mad. Off idle ....not flooring it just a aggressive pedal apply I'm in boost in less than 30 feet. I was skeptical that it would be a little laggy but man it's far from that! Thanks to Cal and Holly at Hartline performance as well as PTE for great service and product.

Turbo nasty and more seat time with that turbo? I should have my build done in a month. Almost the same as yours. Dying to try that turbo on my build. Thanks for any input.

We (our car club) just had Cal Hartline @HighPSI up here for a tune session (Great experience!!). Car made 521 HP and 524 TQ to the tires 24-26 psi on a superflow dyno (thatd be 545ish on a dynojet) and car was breaking up around 5300 and fuel pump cant keep up. Cal told me that FAST system saved my engine as it cracked the INJ PW way open to compensate for the falling Fuel PSI to keep AFR's in line where the stock computer would have expired the engine.
Plenty more horses on the table im thinking 28-30 PSI and proper fueling it'll be upper 500's or low 600's!
Great thing was the TQ and HP was flat and stayed together all the way up!
Going to slap a Walbro 430 LPH in tank/KB Boost a pump (just in case) and better return line and retune.

Nice job brother. ..I think your numbers will go up quite a bit. Shane ( blackgn1) has been 6.3x with his 6466 ...

Turbo nasty any hp numbers or et with 6262 for comparison to the 6466 ? That 6466 is an impressive turbo for sure.

Unfortunately I never got any numbers with the 6262 just street action and butt dyno, it's a sweet turbo tho. Spec wise the 6262 has the PTE CEA wheel on the compressor side only and can be had in JB or BB. Where the 6466 has both CEA wheels and is only available in BB all of this helps its lbs/min up rating to be superior to the 6262. Hard to say a compare tho since the ported alum ta head change is a big step in flow from champ irons which will impact spool etc and it's clear the airflow is significantly higher since the fuel pump couldn't keep up even with 14 volts. At any point whether off idle or light cruise the 6466 will make boost before you can say the word boost lol. Hoping to have fuel pump in soon....going to use a custom hanger so the fab and logistics on that will slow install it a bit. Hoping to have the boost a pump in by the weekend and see if that will at least help the range of the current pump with the boost turned down.

Here's a snap of one of the dyno pulls. Had to hit it from 65 since it kept downshifting to 2nd.

Any update on your combo with that 6466? New dyno #s or drive time impression? Thanks turbo nasty
