looking at the list, how about ignition mods like, Iridium plugs, Granatelli wires and coils like the MSD? That should add atleast another 10hp-15hp.

15hp from plugs and wires?

The coils aren't even necesary on a bolt on car.

The test I saw was actually done on a modified 97 Corvette, with MSD coils, NGK IX plugs and Granatelli wires. So, although the coils might not be necesary on a bolt on car, they are still a bolt on.

Anyone else have any experience seeing a hp gain with a hotter ignition?

now that goes with some of the manuf. advts. when they say that plugs and wires add 15 hp. its true. but on there crazy big hp motor, best tune, and etc. just like a lid does 25 hp, filter 10 hp, and exhaust 25, but that doesnt mean that you get 60 total hp. that is there best the manf. ever got plus a lil strectiong.

hand held tuner diablo, want me a dyno tune before long to see how it does.

**kyemt** · 08-27-2007, 02:07 PM

i wish there was a dyno near me so i could see what my bolt ons have done and se what im putting down and get that tune

**Vexzer** · 08-28-2007, 12:56 PM

for 400rwhp you better bolt on nitrous or a blower...

RWHP ...yes they are.....I've seen quite a few bolt on 04 Goats put that down....

**Kamauxx** · 12-29-2007, 04:11 PM

First post you said 330 with full bolt ons, I'm talking stock.

Are you saying they're 330 AT THE WHEELS from the factory floor?

**Sarge** · 12-31-2007, 12:55 PM

Yes....some are as low as 290'ish...some are around 330'ish....dont ask me why...but we have seen stock GTO's running 30-40RWHP difference bone stock.

**Kamauxx** · 01-01-2008, 09:39 AM

Wow, that's news to me. Wish I could have got one of those freak ls1s for my Z.

**qwik219d9** · 07-04-2009, 03:43 AM

are roller rockers considered boltons?

w/ stock size 1.7 ratio about how much power could be gained if any?

I'm thinking it's also a precaution because you never know when the GM bearings will fall out and ruin the motor right?

Thanks
