Insight Needed From Boosted Owners/Builders - Need Advice

The torque on a centrifugal like a vortech is the most forgiving on internals as it ramps in perfectly linearly. It's that shotgun of torque from a Whipple or turbo low in the rpm range that is harsh on them.

I saw your kits are $5999, that's an amazing deal for a new full A2A kit. My question is how much WHEEL hp is that good for ? Torque?

Is that whp/tq safe for the 7A in stock form?

And anything else I NEED to make it work? I.e, fuel management, etc. or is it just recommended ?

also is the Tial QRJ in your package or an extra amount? Want more info. If I can get away with spending 6k on kit, re tune and be at 450-500whp safely on a 7A I'd be interested.

I already have a 340lph FP, tuned on UpRev with a tuner who can remote tune me on a local dyno. So what else would I be out besides the 6k?

keep saving... if your going a vortech based kit you will want atleast $10k as a budget for the ohh **** or buffer needed in case something breaks. with the whipple or single turbo I would say $15k and twin turbo $20k

I also already answered the 7at capacity question. 400-420ftlbs peak anything above that is borrowed time... even at this level its borrowed time.

Well TG kit says around 450whp which equates to 360 ish TQ (from what dyno logs I've searched around and found) so that's a little under the 400-420 TQ range, correct?

I'm not like most folks on here who say you need to have a bazillion dollars to boost....but your 7AT is the real problem. We haven't yet defined what is "safe" for that trans. It appears any boosted build on that stock 7AT is at risk of the trans failing and the options for built 7AT's appear both iffy and expensive. I know it's not the answer you wanted, but if you are on a budget then boosting an auto Z is going to require a significantly higher risk appetite than boosting in general (which carries its own share of risk already).

If you decide you want a boosted Z, find a cost effective way to exchange your car for a manual to boost or buy someone else's build that has a known good history (if such a thing even exists). Otherwise, it looks like a departure from the Z is in your future.

Sounds like a departure is soon to come as well.
