I recently purchased a used, mint condition Harrop TVS HTV1320-LSJ from another member off here. (Frost289) I got the stock pulley with a 2.8" pulley and 80# injectors for $800. He said the supercharger has roughly 30,000KM on it which is fine. I am so excited. I still need to find a 3" exhaust, maybe a new intake, and meth, with OntarioKev's tune he said he made 310whp and 280wtrq with a 11.5 AFR and 20* of timing on meth. I'd be more than happy with that.

All said and done, I will be tracking it sometimes and hope to hit low 13's at least and possibly high 12's... oh and hopefully don't snap axles. Lol.

What's the best 3" exhaust that sounds good with no rasp and doesn't drone? I know that 3" is going to be loud. I might get a custom one bent.

I was also thinking of getting the LS4 throttle body because mine is bent... I'm not sure how the previous owner did it but he was a retard.

 

Awsome Bro Keep us posted, Would expect the timing to be closer to 27ish though on a tvs and meth.

 

i got the zzp 3" and it is a little raspy when cold but once warmed up its sex!

 

You have pm's boss

 

I currently have a 2.5" Magnaflow muffler and it does the exact same thing. I'm pumped, pm sent.

 

800 dollars for all of that is AMAZING
congratulations, I wish i could get one for that cheap

 

those damn warm up periods

 

Do a custom system buy the tubing kit from mandrel exhaust systems and get a magnaflow resonator and the largest super turbo muffler you can you can't go wrong with that setup

 

800 bux...lol if I found a tvs alone that cheap id buy it in a heart beat haha....

nice setup sir & good luck

 

I literally think you stole that from him...


awesome buy. All 3inch will be loud. If you want limited/no rasp, stick w/ a cat (or high flow), huge res, huge chambered muffler.

 

Only reason I bought it was because of the price. I can locally get someone to mandrel bend me an exhaust. I know that 3" is going to be louder but I want to have no rasp, at the very least. I have a catted 3" downpipe.

Send me videos of that exhaust when it's warm. I'd like to hear it.

 

I just installed the TVS and what a difference. I have yet to tune it so I haven't really tried the full potential but I can feel it already. It's insane.

 

dang! your makin me stoked! i get mine on tues!

 

the tvs makes the car a different beast. and another vote for the zzp its teh sex when it warms up and it flows great as well

 

it sure does and i heard with a port and polished head it opens it up even more! im so excited!

 

a port and polish on the head will open anything up. now you just need a man pulley and run that thing hard.

 

Whats the status on it being on the car. Did you actually get it yet. Also who is tuning this thing for you?

 

G11's is coming with a 2.6

 

Ported head makes a world of difference!

 

^^^^ lookin forward to seeing some of your vids. this year with the new head.

 

agreed

 

If your talking to me your in for a treat Got some tonight Ill post up in the racing section tomorrow

 

The person tuning it is a member on here. OntarioKev; I'm using the nearly the exact setup as the previous owner, I will have a 2.8" with meth injection and the 80#'s after the tune. I currently have the 3.15" with my 60#'s... I will keep you all posted. I'm sure you will net better numbers than I will but I am very happy with what it has already.

 

oNtariokev does very nice tunes

 

I am pumped that he is going to tune my car. I can't wait. Heck, 300+whp will be plently for me. I know he knows what he is doing. I only wish I knew what he knew. If I ported my head I would be pumped... maybe that will be a future mod.
